Question

A company made a profit of $90,000 in the year 2006. In 2010, the same company made a total profit of $135,000. If the rate of change is a constant, what is the average rate of change of the company’s profit in dollars per year? HELP

Answer 1

Answer:

Average rate of change = $11250 per year.

Step-by-step explanation:

Let's take two points from given information (2006, 90000) and (2010, 135000).

Now, use slope formula to find slope.

Slope =$\frac{y2-y1}{x2-x1}$

Use the two points to find average rate of change (slope)

Average rate of change =$\frac{135000-90000}{2010-2006}$

                                        =$\frac{45000}{4}$

                                       =11250

Average rate of change = $11250 per year.
