A parking garage charges the rate in the table below. What is the rate of change? Don’t forget your units.

Question

number of hours (1) (3) (5)
cost of parking ($10) ($14) ($16)

Answer 1

To find the rate of change, we need to determine how much the cost of parking changes for each additional hour.

For the given data, the cost of parking increases by $4 from the first hour to the third hour (10 to 14) and then increases by $2 from the third hour to the fifth hour (14 to 16).

Therefore, the rate of change for this parking garage is $4 per hour.
