Question

Mr. Frankel bought 9 tickets to a puppet show and spent $70. He bought a combination of child tickets for $5 each and adult tickets for $10 each. Write a system of equations that can be used to determine the number of adult tickets, a, and the number of child tickets, c, he bought.

Solve by elimination

Answer 1

Explanation:

let $5 tickets is X

so.. $10 = 9-x

now.....

5x + 10(9-x) = 70

so...

5x = 20

X = 4

hence

$5::: 4

$10::: 5
