At the end of the summer, Walgreens advertised blow-up pools for 66% off the regular price. Jeff Jones saw a pool with a regular price of $49.99. What is the dollar markdown? A. $32.99 B. $33.99 C. $33.39 D. $39.29

regular price = 49.99
66% of regular price = 0.66*49.99 = 32.9934 which rounds to 32.99

So the dollar markdown is $32.99 meaning you save that much money.
