Textbook Problem

The total cost of producing 1 unit of a product is given by

*x* is the hourly labor rate and *y* is the cost per pound of raw materials. The current hourly rate is $25, and the raw materials cost $6 per pound. How will an increase of

(a) $1 per pound for the raw materials affect the total cost?

(b) $1 in the hourly labor rate affect the total cost?

**(a)**

To determine

**To calculate:** The increase in total cost for each increase of $1 per pound of the raw materials. The total cost of producing 1 unit of a product is given by *x* is the hourly labor rate and *y* is the cost per pound of raw materials. The currently hour rate is $25, and the raw materials cost $6 per pound.

Explanation

**Given Information:**

The total cost of producing 1 unit of a product is given by *x* is the hourly labor rate and *y* is the cost per pound of raw materials. The currently hour rate is $25, and the raw materials cost $6 per pound.

**Formula used:**

The rate of change of a function *y* is given by the partial derivative of *f* with respect to *y*.

For a function *f* with respect to *y* is calculated by taking the derivative of *y* and keeping the other variable *x* constant. The partial derivative of *f* with respect to *y* is denoted by

Power of

Constant function rule for a constant

The coefficient rule for a constant

**Calculation:**

Consider the problem, the total cost of producing 1 unit of a product is given by

**(b)**

To determine

**To calculate:** The increase in total cost for each increase of $1 hourly labor rate. The total cost of producing 1 unit of a product is given by *x* is the hourly labor rate and *y* is the cost per pound of raw materials. The currently hour rate is $25, and the raw materials cost $6 per pound. Interpret the answer.
