Harriet Robinson's Account of Lowell Mill Girls

Harriet Robinson's intended audience for her firsthand account of life as one of the "Lowell Mill Girls" appears to be a combination of several groups, including:

  1. Contemporary Society and Reformers: Robinson wrote her account in 1883, a time when labor reform and women's rights were gaining momentum in the United States. By detailing the struggles and conditions faced by mill girls, she aimed to raise awareness among social reformers, labor activists, and the general public about the harsh realities of factory life. Her emphasis on the long working hours, low wages, and the plight of young girls in the mills serves to highlight the need for labor reforms, such as the ten-hour workday law that was eventually passed.

  2. Women and Future Generations: Robinson's narrative also targets women, particularly those who might be considering factory work or who are already in similar positions. By sharing the experiences of the mill girls, she seeks to empower women by illustrating their contributions to society and the economy, as well as the sacrifices they made for the education and betterment of their male relatives. This aspect of her account serves to inspire future generations of women to advocate for their rights and seek better opportunities.

  3. Historians and Scholars: Robinson's detailed observations about the socio-economic conditions of women in the early 19th century provide valuable historical context. By documenting her experiences and the collective actions of the mill girls, she contributes to the historical record, making her account relevant for historians and scholars studying labor history, women's history, and the industrial revolution in America.

  4. General Public: Finally, Robinson's writing is also directed at the general public, aiming to challenge prevailing stereotypes about factory workers, particularly women. By countering the negative perceptions of mill girls as "brutes" or "slaves," she seeks to elevate their status and promote a more nuanced understanding of their lives and contributions.

In summary, Harriet Robinson's intended audience includes contemporary reformers, women, historians, and the general public. Through her account, she aims to raise awareness of the struggles faced by mill girls, advocate for labor reforms, and challenge societal perceptions of working women in her time.

Change in Oil Production Costs Analysis

To determine the change in total costs of production when producing 1 less barrel of oil from Oil Pump One and 1 more barrel of oil from Oil Pump Two, we need to compare the marginal costs of the barrels being produced.

Currently, the production is:

  • Oil Pump One: 6 barrels
  • Oil Pump Two: 2 barrels

Current Costs:

  • For Oil Pump One (6 barrels): The marginal cost of the 6th barrel is $30.
  • For Oil Pump Two (2 barrels): The marginal cost of the 2nd barrel is $12.

New Costs after the change:

  • If we produce 1 less barrel from Oil Pump One (5 barrels), the marginal cost of the 5th barrel is $25.
  • If we produce 1 more barrel from Oil Pump Two (3 barrels), the marginal cost of the 3rd barrel is $14.

Calculating the change in total costs:

  1. Current cost of producing the 6th barrel from Oil Pump One: $30
  2. New cost of producing the 5th barrel from Oil Pump One: $25
  3. Current cost of producing the 2nd barrel from Oil Pump Two: $12
  4. New cost of producing the 3rd barrel from Oil Pump Two: $14

Total cost change:

  • Cost decrease from Oil Pump One: $30 (for the 6th barrel) - $25 (for the 5th barrel) = $5 decrease
  • Cost increase from Oil Pump Two: $14 (for the 3rd barrel) - $12 (for the 2nd barrel) = $2 increase

Net change in total costs:

  • Total change = Cost decrease from Oil Pump One - Cost increase from Oil Pump Two
  • Total change = $5 (decrease) - $2 (increase) = $3 decrease

Since the options provided do not include a decrease of $3, let's re-evaluate the options based on the calculations:

  • The total costs of production fall by $16.
  • The total costs of production fall by $30.
  • The total costs of production rise by $7.
  • The total costs of production rise by $14.

None of these options match our calculated decrease of $3. However, if we consider the closest option, it seems that the calculations might have been misinterpreted or the options provided do not align with the calculations.

Based on the calculations, the total costs of production should fall, but the exact amount does not match any of the provided options. If we strictly follow the calculations, the answer would be that the total costs of production fall, but the exact amount is not listed.

If we had to choose the best answer from the options provided, we would note that the total costs are indeed falling, but none of the options accurately reflect the calculated change.

Change in Total Production Costs Analysis

To determine the change in total costs of production when producing 1 less barrel of oil from Oil Pump One and 1 more barrel of oil from Oil Pump Two, we need to compare the marginal costs of the barrels being produced.

  1. Current Production:

    • Oil Pump One: 6 barrels
    • Oil Pump Two: 2 barrels
  2. Marginal Costs:

    • For Oil Pump One (6 barrels): $30
    • For Oil Pump Two (2 barrels): $12
  3. Change in Production:

    • Decrease 1 barrel from Oil Pump One (from 6 to 5 barrels).
    • Increase 1 barrel from Oil Pump Two (from 2 to 3 barrels).
  4. New Marginal Costs:

    • For Oil Pump One (5 barrels): $25
    • For Oil Pump Two (3 barrels): $14
  5. Calculating Total Costs:

    • Current Total Cost:

      • Cost from Oil Pump One (6 barrels): $30
      • Cost from Oil Pump Two (2 barrels): $12
      • Total Cost = $30 + $12 = $42
    • New Total Cost:

      • Cost from Oil Pump One (5 barrels): $25
      • Cost from Oil Pump Two (3 barrels): $14
      • Total Cost = $25 + $14 = $39
  6. Change in Total Costs:

    • Change in Total Cost = New Total Cost - Current Total Cost
    • Change in Total Cost = $39 - $42 = -$3

Since the total costs of production fall by $3, none of the provided options are correct. However, if we consider the marginal costs of the barrels being produced, we can see that the total costs decrease when switching production from a higher marginal cost barrel to a lower marginal cost barrel.

If we were to analyze the options again, it seems there might be a misunderstanding in the calculations or the options provided. Please double-check the marginal costs and the quantities to ensure accuracy.
