How many child tickets were sold that day?

Question

At the city museum, child admission is $5.60 and adult admission is $8.80. On Wednesday, four times as many adult tickets as child tickets were sold, for a total sales of $856.80.

Answer 1

child admission = 5.6

 

adult admission = 8.8

 

total sale = 856.8

 

C = number of children

 

A = number of adults

 

A = 4C (given)

 

Math model of the problem:

 

5.6C + 8.8A = 856.8

 

5.6C + 8.8(4C) = 856.8

 

C = 21

 

A = 4(21) = 84

 

They sold 21 child tickets and 84 adult tickets.
