Question

An adult ticket to the zoo costs $20 and a child's ticket costs $10. How much will it cost for Mr. and Mrs. Brown and their 4 children to get into the zoo?

Answer 1

$80 20+20=40. 10+10+10+10=40.
40+40=80

Answer 2

For the adults it would be 40 and for the children it would also be 40 which adds up into a sum of 80 hope it helps :)
