Question

At the city museum, child admission is $6.40 and adult admission is $9.50. On Friday, 150 tickets were sold for a tatal sales of $1260.70. How many child tickets were sold that day?

Answer 1

x child tickets, y adult tickets

6.40x+9.50y=1260.70

x+y=150

 

64x+95y=12607

x+y=150

If you solve this, you have to get x=53, y= 97.

So 53 child tickets and 97 adult tickets.
