The price of a movie ticket at the theater is $7 for students. The price is higher for adults. A group of 4 students and 3 adult

Marat540 [252]

Given:

Student ticket price = $7

A group of 4 students and 3 adults paid $64 in all for movie tickets.

To find:

Each of the adult ticket cost.

Solution:

Let x be the cost of each adult ticket.

Then, cost of 3 adult tickets = 3x.

Cost of 1 student ticket = $7

Cost of 4 student ticket = $7(4)

According to the question,

$7(4)+3x=64$

$28+3x=64$

$3x=64-28$

$3x=36$

Divide both sides by 3.

$x=12$

Therefore, the cost of each adult ticket is $12.
