The equation that can be used to model the total cost is y = 18x

What equation can be used to model the total cost?

The given parameters are:

Cost = $72

Time = 4 hours

The hourly rate is calculated as:

k = Cost/Time

So, we have

k = 72/4

Evaluate

k = 18

The form of the equation is given as
y = kx

Substitute k = 18 in y = kx

y = 18x

Hence, the equation that can be used to model the total cost is y = 18x
