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

(1,10)
(3,14)
(5,16)

To find the rate of change, we need to calculate the change in y-values (parking charges) divided by the change in x-values (time in hours).

The change in y-values is 16 - 10 = 6.
The change in x-values is 5 - 1 = 4.

Therefore, the rate of change is 6/4 = 1.5.

The units for this rate of change would be the change in parking charges per hour or $/hour.
