Mr. wilson wants to park his car in his parking garage. to find the cost, he uses the equation d= 3h+6, where d represents the total amount, in dollars, charged for parking a car for h hours. if mr. wilson spent $30, how many hours did he park in the parking garage?

Step-by-step explanation:

You know that Mr. Wilson uses the following equation to find the cost:

Then, if Mr. Wilson spent $30, you can follow these steps in order to calculate how many hours he parked in the parking garage:

1. You need to substitute into the given equation:

2. Now, you must solve for "H":

Therefore, based on the result, you can conclude that Mr. Wilson parked his car in the parking garage for 8 hours.

k = 9/4

Step-by-step explanation:

To find k, use the equation

y = kx

Pick a point

72 = k *32

Divide each side by 32

72/32 = k

9/4 = k
