Question

A married couple and their 4 children buy tickets to a ball game. The tickets cost 25 dollars a piece, but each of their children gets a 20% discount. How much, in dollars, must the family pay for tickets?

Answer 1

Price of an adult ticket: $25

Price of a child's ticket is 25-0.20(25) = $20

Total cost = 2 adult tickets + 4 child tickets

= 2(25)+4(20)

= 50+80 = $130
