Question 819489: Sammy decided to go Christmas shopping at the mall. He had won a pass that allowed him to take an additional 20% off all final price purchases at any store, which he used for each purchase. First Sammy went to Game Stop to by his friend a video game. Game stop was having a 35% off store-wide sale. Then, he headed off to Payless to take advantage of their 25% off everything sale, to buy a pair of shoes. His last stop was at Moosejaw to buy a pullover, because they were having a one-day sale where everything was 15% off. As Sammy was leaving the mall, he stopped at a gift wrapping booth. They were charging $2.75(tax-included) for each gift wrapped. Sammy had all three gifts wrapped.
At the end of the month Sammy opened his credit card statement and noticed the following three charges:
Game Stop: $35.28
Payless: $55.72
Moosejaw: $96.89
What was the original price of each item AND what was the average dollar amount Sammy spent on each purchase?
Using MICHIGAN sales tax! 6%
What I already solved:
1. Work backwards
2. Undo the tax
3. $55.72 - $3.15 (tax)= $52.57
$35.28 - $2.54 (tax)= $32.74
$96.89 - $5.48 (tax)= $91.41
4. Undo the percent off
5. Total of 45% saved at Payless
Total of 55% saved at Game Stop
Total of 35% saved at Moosejaw
*This is the part of the process I don't understand
