The rate of discount, r, can be determined using the formula , where p is the regular price of an item and d is the discount, or amount saved off the regular price. find the rate of discount on a sweater with a regular price of $36 that is on sale for $27. if necessary, round to the nearest hundredth. 1.25 1.75 0.75 0.25

The rate of discount on the sweater is 0.25

Step-by-step explanation:

Given

Regular price of the sweater , P = $36

Price at which sweater is sold after the discount , S= $27

Thus discount on sweater , D= P - S

=> D= $(36-27) = $9

Now if R is the rate of discount then

D= RxP

=>

Thus the rate of discount on the sweater is 0.25
