Question

Fran wants to rent a scooter for the afternoon, but she can spend no more....

Answer 1

It is 6 hour because if you multiply 7.50 which is 35.50 then add 12.50 that will come out to 50

Answer 2

12.50 + (7.5)(h-1) ≤ 50

6 hours or less

Explanation:

The first hour is 12.50. Each additional hour is 7.50

Let h be the number of hours

12.50 + (7.5)(h-1)

We use h-1 since the first hour is 12.50

This must be less than or equal to 50

12.50 + (7.5)(h-1) ≤ 50

Now we solve the inequality

Subtract 12.50 from each side

12.50-12.50 + (7.5)(h-1) ≤ 50-12.50

(7.5)(h-1) ≤ 37.50

Divide by 7.5 on each side

(7.5)/7.5(h-1) ≤ 37.50/7.5

h-1 ≤ 5

Add 1 to each side

h-1+1 ≤ 5+1

h ≤ 6

We can only rent for 6 hours or less
