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.

Question

How many friends can Jose invite if he wants to spend only $50.00 total on skate rentals?

Jose can invite____friends.

Answer 1

16 friends.

Calculation:
Let x be the number of friends Jose can invite.
Total cost = (x + 3) * $2.50
$50.00 = (x + 3) * $2.50
$50.00 = $2.50x + $7.50
$42.50 = $2.50x
x = 17

Since Jose is included in the number of friends, he can invite 16 friends to his roller skating party.
