Question

When 2 parents and 3 children visit a theme park the admission cost is $57. The cost is $33 for 1 parent and 2 children. Find the cost for 1 adult and the cost for 1 child?

Answer 1

2*P + 3C=57

P+2C=33

double the second equation, then subtract it frm the first.
2P+3C=57
2P+4C=66

-c=-9
cost for child is 9 dollars. Now put that into the first equationo, and solve for A cost
