Question

A store is having a sale where all jeans are 1/4 off the regular price. Find the constant of proportionality, then write an equation relating the sale price to the regular price. How much would a pair of $29 jeans cost on sale?

Answer 1

sale price is $21.75

Explanation:

A store is having a sale where all jeans are 1/4 off the regular price.

Let x be the regular price and y be the sale price

sale price = regular price - 1/4 of regular price

`y=x-(1)/(4) x`

`y=(3)/(4) x`

equation relating the sale price to the regular price is

`y=(3)/(4) x`

regular price of jeans is $29

so sale price is

`y=(3)/(4)(29)`

y=21.75

sale price is $21.75
