Question

At the movie theatre child admission is $6.30 and adult is $9.90 on Monday, 138 tickets were sold for a total sales of $1053.00. How many tickets were sold that day

Answer 1

Answer: 87 children and 51 adult

Explanation:

Let x be child admission and let y be adult admission.

We know that x+y=138 based on the fact that 138 tickets were sold.

We also know that 6.3x+9.9y=1053 based on the information.

Let y=138-x

Then, 6.3x+9.9(138-x)=1053

6.3x+1366.2-9.9x=1053

-3.6x+1366.2=1053

-3.6x=-313.2

x=87

138-87=y=51

87 children's and 51 adult tickets were sold.
