If everything in the store is 40% off, then you can assume that the discount is .4*p, so the equation for the amount of discount would be d=.4p 

The equation for the sale price of an item would be the starting price, p, minus the discount price, d. If we write this equation, we get S=p-d. Since we already solved for d, we can plug that into this new equation to get s=p-.4p.  If the regular price is $85, then we can plug that in for p.

when it is plugged in, we get s=85,.4(85). Simplify this and you get s=85-34 or s=51. This means that the sale price would be $51

a. The function that represents the amount of discount on a regular price is: d = 0.4p

b. The sales price of the bookshelf is $51.

A discount is when the price of an item is reduced. The value of a discount can be determined by multiplying the price of an item by the percentage discount.

Discount = original price x percentage discount

$85 x 40%

$85 x 0.4 = $34.

Sales price = original price - discount

$85 - $34 = $51
