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.

Answers

Answer:

Jose can invite 16 friends.

Step-by-step explanation:

For roller skating, the skate rentals charge $2.50 per person.

Jose has to invite friends and wants to spend a total of $50.

$50 / $2.50 = 20

So, for $50.00, 20 people can enjoy roller skating.

Out of these 20 people, one will he Jose himself and 3 will be the adult chaperones.

20 - 4 = 16

Therefore, Jose can invite 16 friends for roller skating.

Jose can invite 46 of his friends, given that there isn't tax. Because with a ticket costing $2.50 a person, and he at least knows that 50 people can go, and that 4 people are planning to, and are going to skate already.
