Write an expression that means eighty percent of twenty five dollars. Make sure that the expression is equal to the sale price you calculated above. 3. The regular price of a softball glove is $80. 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.
