Question

Walter describes his monthly profit, p, in terms of the number of jobs he performs, j, using the equation p = 75j - 650. What is Walter's rate of change in profit with respect to the number of jobs he performs?

A) 75
B) -650
C) 75j
D) -650j

Answer 1

Walter's rate of change in profit with respect to the number of jobs he performs is $75 for each additional job, represented by the slope of the profit equation.

Step-by-step explanation:

The rate of change in profit with respect to the number of jobs Walter performs is represented by the coefficient of j in the equation p = 75j - 650. This coefficient is the slope of the profit line, which indicates how the profit changes as the number of jobs changes. The rate of change is the slope of the line, which is 75. This means for each additional job Walter performs, his profit increases by $75. Therefore, the correct answer is A) 75.
