Question

A group of 8 friends each buy 1 ticket and 1 small popcorn

at the movie theater. Each ticket costs $7.50. The group of
friends spends a total of $83.60.

Enter the cost of 1 small popcorn.

Answer 1

$2.95

Explanation:

8x+8y=83.60

8 is the amount of friends/amount of tickets/amount of small popcorn

x is the cost 1 ticket

y is the cost 1 small popcorn

We know that the price of a ticket is 7.50 so we replace "x" with 7.50

8(7.5)+8y=83.60

Simplify

60+8y=83.60

Now subtract 60 from both sides

8y=23.60

Now divided both sides by 8

y=2.95

the cost of 1 small popcorn is $2.95
