Question

jon has to pay $9 admission for the skating rink and $2 per hour to rent rollerblades. how many hours can he skate for $19?

Answer 1

Jon can skate for 5 hours.

Jon has to pay $9 for admission and $2 for skates for the first hour. This means so far he has paid $11. Now u have to add $2 for each hour that he skates. Remember, he only had $19 so u would stop adding $2 until u hit $19. After you keep adding $2 for every hour, you would end up with 5 hours.

Here is some work:

(1hr) 9+2=11
(2hr) 11+2=13
(3hr) 13+2=15
(4hr) 15+2=17
(5hr) 17+2=19

This means that Jon can skate for 5 hours if he has $19.
