Question

Two parts: Make sure to answer EACH part:

1. What is the rate of change for each shop shown below?

2. Which shop has the GREATEST rate of change?

Answer 1

Rate of change for Carol's = 4.99

Rate of change for Wilma's:

line passes through (0, 0) and (2, 15)

slope = m = (15 - 0) / (2 - 0) = 7.5

Rate of change for Wilma's = 7.5

7.5 > 4.99

So Wilma's has the greatest rate of change.
