Question

erin rented a stand-up paddle board (SUP) while on vacation. She paid an initial rental fee of $15 and then $8.50 per hour. If she paid a total of $49.00, how many hours did she rent the SUP?

Answer 1

Let no of yours be x

The equation is

• y=8.5h+15

Put y=49

• 49=8.5h+15
• 8.5h=34
• h=4hours

Answer 2

• 4 hours

Explanation:

The equation to show the total charge:

• c(h) = 15 + 8.5h, where h is the number of hours

Substitute 49 into equation and solve for h:

• 15 + 8.5h = 49
• 8.5h = 34
• h = 34/8.5
• h = 4
