Need help on part B.

### Production Cost Analysis

The total cost of producing one unit of a product is given by the following function:

\[ C(x, y) = 80 + 0.3x^2 + 50y - xy \, \text{dollars} \]

where \( x \) is the hourly labor rate and \( y \) is the cost per pound of raw materials. The current hourly rate is \( \$27 \), and the raw materials cost \( \$2 \) per pound.

#### (a) Effect of a $1 Increase per Pound for Raw Materials:

**Question: How will an increase of $1 per pound for the raw materials affect the total cost?**

- **Answer:** The total cost will **increase** by **$23**. ✔️

#### (b) Effect of a $1 Increase in the Hourly Labor Rate:

**Question: How will an increase of $1 in the hourly labor rate affect the total cost?**

- **Answer:** The total cost will **increase** by **$14.5**. ❌

This analysis helps in understanding how changes in labor and material costs impact the overall production expenses.
