Question

After 3 hours of waiting tables, Jerome made $25 in tips. After 8 hours of waiting tables, Jerome made $115 dollars in tips. Find the average rate of change of dollars per hour.

Answer 1

Rate of change is slope.
You want dollars per hour.
So, the rate is: change in dollars / change in hours

(115 - 25) / (8 - 3) → 90/5 → 18

The rate of change is $18/hour.
