A Halloween magic show costs $4 for adults and $1 for children under 10. If twice as many children attend as adults and the show received a total of $72, how many adults and how many children attended?

Fairly simple one,

adult + 2 kids = 6$

72$ in total / 6$ = 12

So 12 adults and 24 kids.

to check:

12 adults @ 4$ = 48$
24 kids @ 1$ = 24$

48$ + 24$ = 72$

Hi,
If this is an algebra question, here is the answer:

x = number of adults
2x = number of children

$4(x) + $1(2x) = $72
4x + 2x = 72
6x = 72
x = 12 adults, and,
2x = 24 children.

Same answer as the other post, but in algebraic terms.
Best wishes,
