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?

Respuesta :

Answer:

sale price is $21.75

Step-by-step 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

[tex]y=x-\frac{1}{4} x[/tex]

[tex]y=\frac{3}{4} x[/tex]

equation relating the sale price to the regular price is

[tex]y=\frac{3}{4} x[/tex]

regular price of jeans is $29

so sale price is

[tex]y=\frac{3}{4}(29)[/tex]

y=21.75

sale price is $21.75
