$1114.00

. How many child tickets were sold that day?

Answer provided by our tutors

Let

a = the number of adult tickets sold

c = the number of child tickets sold

There were 150 tickets sold in total:

a + c = 150

The total sales was $1114,00:

8.90a + 5.50c = 1114.00

We have the following system of equations:

a + c = 150

8.90a + 5.50c = 1114
