Question

19. A mattress store sells their stock for 15% off of retail. If someone pays cash, they take an additional 10% off of the discounted price. If a mattress's retail price is $750, what is the price after the store discount and the cash discount?

A. $550.75
B. $562.50
C. $573.75
D. $637.50
E. $675.0

Answer 1

Hint:

When you apply an x% discount, you are multiplying the original price by (100-x)/100

ex:

when you apply a 25% discount, you're really multiplying the original price by (100-25)/100 = 0.75

So if the original price was $600, then applying a 25% discount gives you 600*0.75 = 450 dollars as the sale price
