You can put this solution on YOUR website! An MP3 player costs $80. A student has a coupon for
1/4 off. The student saves $7 per week. Assuming the price of the MP3 player does not change, how long will it take the student to save enough to buy it?
-----
1/4 off reduces the cost to 80-(1/4)80 = 80-20 = $60
----
# of weeks = 60/7 = 8 4/7
Rounding up to whole number of weeks = 9 weeks.
