cora and her family are going to an amusement park. there are 2 adults and 3 children. the tickets cost her family $70. adults are twice as much as children

Question

How much is an adult ticket and how much is a childs Ticket

 

Answer 1

C = child's ticket price

A = adult ticket price

 

We know that

A = 2C

 

and 

2A + 3C = 70

Since A = 2C, let's substitute this in the equation just above

2(2C) + 3C = 70

7C = 70

The cost of a child's ticket is $10 and the cost of an adult ticket is $20.
