answer is 25% off discounts

Answer:

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

=>[tex]R=\frac{D}{P}=\frac{9}{36}=0.25[/tex]

Thus the rate of discount on the sweater is 0.25
