Question

Sashia buys 8 sashes for $12. Write an equation relating the total cost y to the number of sashes x.

Answer 1

`y=(3)/(2) x`

Explanation:

It’s clear that we there is a proportional relationship between the number of sashes and their cost.

then

`(y)/(x) =(12)/(8)`

then

`y= (12)/(8) x`

Or 12/8 = 3/2

Then

`y=(3)/(2) x`
