Question

Someone help with #1

Answer 1

ok, first we set up 2 equations with the given info
let chips = c & pretzels = p


`5c + 9p = 16.95`

`10c + 10p = 22.50`

next we solve for a single variable in one of the equations (I chose the first one)

`c = (16.95 - 9p)/(5)`

now plug it into our second equation

`33.90 - 18p + 10p = 22.50`
simplify

`11.40 = 8p`
divide

`1.425 = p`

next plug p back into our first equation

`5c + 9(1.425) = 16.95`

`5c = 4.125`

`c = .825`

Chips cost = $0.825
Pretzels cost = $1.425
