Question

Adult tickets to the aquarium costs $22 each while child tickets cost 15 each. If a large group buys 32 tickets and paid 543 how many child tickets were purchased?

Answer 1

23 Child Tickets

Explanation:

x = adult ticket

Y = child ticket

X + Y = 32

X= 32 - Y

22X + 15Y = 543

22(32 - Y) + 15Y = 543

704 - 22Y + 15Y = 543

-22Y + 15Y = -161

-7Y = -161

Y = 23

Answer 2

23 child tickets

Explanation:

9 adult tickets

23 child tickets

543-22*9=345

345/15=23

9+23=32 tickets total
