Aparking garage charges the rates in the table below. what is the rate of change.

number of hours[1] [3] [5]

cost of parking [10] [14] [16]

y- dependent variable

Now, rate of change =

Here , the rate of change = $ 2 per hour.

Again rate of change =

Here , the rate of change = $ 1 per hour.

Since both rate of changes are not equal , it means the rate of change is not constant.

i think it would be 42cm

so, converting firstly the mixed fractions to improper fractions and then "adding".
