Can you please assist with this question:
At a school production, adult tickets cost $7.00 each and student tickets costs $4. The Johnson family is going to the 7:30PM show and will purchase half as many adult tickets as student tickets. If the Johnsons will spend $45 on tickets, how many total tickets did they buy?
X = 7.00 adult ticket
Y = 4.00 student ticket
x + y = 45
1/2x + y = 45 ?

number of adult tickets --- x
number of student tickets -- 2x
7x + 4(2x) = 45
15x = 45
x = 3
so they bought 3 adult tickets and 6 student tickets.
check: is the number of adult tickets half of the student tickets ? YES
what is the cost:
7(3) + 4(6) = 45
