Question

A ski club with 28 members went on a ski trip. Some members rented skis and the rent for $16.00 a day and snowboards rent for $19.00 a day, and the club spent $478.00 in rentals, how many ski club members rented skis?

Answer 1

`18`

Explanation:

`x+y=28 => x = 28-y`

`16x+19y=478`

`16(28-y)+19y=278`
`448-16y+19y=478`
`3y=30`
`y=10`
`x=18`
