It is on sale for 40% off. What is the sale price?

Explanation / Answer

(b). If 20% is taken off the regular price, one has to pay (100 -20)% = 80% of the regular price

( c). The sale price as a percentage of regular price is (20/25)*100 = 80%

(d).    80% *($25) = (80/100)*($25) = $ 20

      3. The discount on the price of the softball is 40% of $ 80 = (40/100)( $80) = $ 32. Hence the sale price of the softball = regular price –discount = $ 80 -$ 32 = $ 48.
