Answer:
The rate of discount on the sweater is <u><em>0.25</em></u>
<u><em></em></u>
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 <u><em>0.25</em></u>
