Children's tickets to a movie cost $7.00. Adult tickets cost $12.00. If 1275 tickets were sold for a total of $2490.00, how many of each type were sold?

Answer 1

There must be a typo, because the cheapest ticket is $7, which when multiplied by 1275 gives 8925, much higher than the revenue of $2490.

Assuming total of 275 tickets sold.

x=number of adult tickets
275-x=number of children's tickets

Then
12x+7(275-x)=2490
Solve for x to get x=113
so
113 adult tickets,
162 children's tickets.
