Maldonado · Answer 1

10+2.5h=7+4h, h=2

Step-by-step explanation:

If you want to find where the costs would be the same, you must set the 2 sides to be equal to each other. SkateWorld has a flat fee of $10 and $2.5 for every hour, while IceLand has a flat fee of $7 and $4 per hour. The equation would look like 10+2.5h=7+4h, where h is the number of hours renting ice skates. After isolating h we get 3=1.5h, then we divide each side by 1.5 and end with 2=h.
