Question

A new shoe company is trying to compete with Nike. They are measuring their profit over the course of 6 months to see if their profit model is allowing them to earn maximum profit. After month 3 they have made a profit of $15,500. After month 6, they made a profit of $22,000. Assuming that their profit can be modeled by a linear function, the average rate that the company earns profit is approximately _____with a unit of _____

Answer 1

(C)2167

(B) dollars/month

Step-by-step explanation:

0. After month 3, they have made a profit of $15,500.

,

1. After month 6, they made a profit of $22,000.

The average rate that the company earns in profit will be:

`\begin{gathered} \text{Slope}=(22000-15500)/(6-3) \\ =(6500)/(3) \\ =2166.7 \\ \approx2167 \end{gathered}`

Recall that we divided the change in profit by the change in the number of months, therefore, the unit is:

`(B)\frac{\text{dollars}}{\text{month}}`
