The sweater Ingrid wants to buy is $30.
It is on sale for 33% off. If the sales tax is
7%, what is the total cost of the sweater?
Round to the nearest cent, if necessary.
The answer is $21.40. You first figure out what the discounted price of the sweater is (which is $20). Then you multiply 20 by 1.-7 since the tax on it is 7%. Thus your answer is $21.40
