Question

A family purchased tickets for a concert. They paid a total of $90.00 for 7 adults tickets and 12 child tickets. The price of a child ticket 2/3 the price of an adult ticket. How much is the price of one adult ticket.

Answer 1

The equation is like this 12x + (2/3)7x =90
Simplify
12x+(14/3x)=90
(50/3)x= 90
x= 90/(50/3)
x= 5.4
