Question

Tickets to a movie cost $9 for each adult and $4.50 for each child. Molly purchased 11 tickets for $72.



How many adult and how many child tickets did she purchase?



Molly purchased adult tickets and child tickets.

Answer 1

$9 for each adult
$4.50 for each child
11 tickets for $72
Do you have any options?

Answer 2

I think that this can be solved using simultaneous method,

A for Adults and C for Children

so 9A + 4.5C = 72
and A + C = 11

A = 11-C

substitute

9(11-C) + 4.5C = 72

99 - 9C + 4.5C = 72
-4.5C = -27
C = 6

A = 5 tickets
