Jose is trying to decide how many friends he can invite to his roller skating party. Skate rentals cost $2.50 per person, including Jose, and he knows that 3 adult chaperones plan to skate.
How many friends can Jose invite if he wants to spend only $50.00 total on skate rentals?
Jose can invite
friends.
16 friends
Calculation:
Total cost for skate rentals for friends and chaperones = $50.00
Cost for Jose and 3 chaperones = $2.50 x 4 = $10.00
Remaining cost for friends = $50.00 - $10.00 = $40.00
Cost per friend = $2.50
Number of friends = $40.00 / $2.50 = 16
Jose can invite 16 friends to his roller skating party.
