At Water World the admission fee is $17.00, and you can rent an inner tube for $0.75 per hour. You can use the formula P = 17.00 + 0.75 h to find the total cost for admission plus renting an inner tube.
a. Solve the formula P = 17.00 + 0.75 h for h. Explain your steps for solving the formula for h.
b. For how many hours can you rent an inner tube if you only have $20.75 to spend? Explain your method for finding the answer

anonymous · Answer

P = 17.00 + 0.75 H
- 17 from each side
P - 17 = 0.75H
divide each side by 0.75
H = (p-17)/0.75
H = (20.75 - 17)/0.75
H = 3.75/0.75
H = 5
