Question

At the bowling alley, Terry paid $22.50 and bowled 3 games while Tommy bowled 2 games and paid $15. Interpret the rate of change by identifying the cost of each game.

Answer 1

The rate of change is $7.50 per game.

Explanation:

Lets set up a table:

Total ($) Games $/Game

Terry 22.5 3 7.5

Tommy 15 2 7.5

Divide the total spent by the number of games (last column).

The rate of change is $7.50 per game. Each additional game will cost $7.50.
