Question

Adult tickets cost 12$, but kids tickets cost just 8$. If a group of 13 people pay for tickets for this adventure park, and they pay $124, how many kids must be in that group

Answer 1

Explanation:

There are x kids in the group

So, adults are 13-x people

(13-x)(12) + x(8) = 124

156 - 12x + 8x = 124

156 - 124 = 4x

4x = 32

x = 8

There are 8 kids in that group.
