Question

A married couple and their 5 children buy tickets to a ball game. The tickets

cost 20 dollars apiece, but each of their children gets a 15 percent discount.
How much does the family pay to go to the game?

Answer 1

Price of an adult ticket: $20

Price of a child's ticket is
`20-0.15(20) = \$17`

`\text{Total cost = 2 adult tickets + 5 child tickets}`

`= 2(20)+5(17)`

`= 40+85 = \bold{\$125}`

Answer 2

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
