An equation that could be used to represent this equation is:
y = 2.5x - 2.5
Step-by-step explanation:
x = number of hours
y = the amount that the user has to pay
You have to multiply the number of hours by $2.50. Then subtract $2.50 from that amount for the first hour that is the parking garage allows the user to park for free.
The inverse operation is a cubed root. It is a square root symbol with a small 3 to the left of the radical. The cubed root of x is a number, when cubed, gives x. For example, .
