Black Friday/Cyber Monday – The Problems
December 1, 2008
On Black Friday, Denise woke up at 3am to make sure she was able to get to the store for the “early bird” special – 60% off all clothing in the store! If Denise paid $50.64 for a dress after 5.5% sales tax, what was the original price of the dress?
Sally has a coupon that she can use in addition to the sales at a particular store. Excited to stock up, she immediately finds two sweaters that are each 30% off and decides to use her “buy one get one half off” coupon to save even more. If the two sweaters were originally the same price, what single percent discount would have resulted in the same savings as Sally’s combined discount?
On Cyber Monday, Bill is able to get 20% off of TVs at his favorite online store. If one TV was originally $699.99 and the other was 749.99, what is the positive difference between the two prices after the discount is applied?
The solutions to this week's problems will be posted in the archive on Monday, December 8th, 2008.
