A jet ski rental company charges h dollars for the first hour its jet skis are rented and k dollars per hour for each hour rented after the first. If a jet ski is rented for t total hours,
where t is an integer greater than 2, which of the following represents the total rental cost
of the jet ski?
h+t+k
B
h+ tk
h+k(t-1)
h+k(t + 1)
h+

C. h + k (t - 1)

Step-by-step explanation:

If we use an example, you can plug in the numbers and test out which equation works. Say the first hours costs $10 and each hour after that is an additional $5. If someone rents a jet ski for 4 hours, how much did it cost?

The first hour = $10

The 3 additional hours (totaled) = $15

Cost = $25

So now that we know the cost, we can plug in our numbers to these equations to find which one comes out with $25.

h = 10

k = 5

t = 4

A. 10 + 4 + 5 = 19

B. 10 + (4 · 5) = 10 + 20 = 30

C. 10 + 5 (4 - 1) = 10 + 5 (3) = 10 + 15 = 25

D. 10 + 5 (4 + 1) = 10 + 5 (5) = 10 + 25 = 35

E. 10 + (4/5 - 1) = 10 + (-0.2) = 9.8

C is the only problem that comes out as $25, therefore it must be the correct answer.

y=1/4x-4
