Problema Solution
An iPod that is usually priced at $239 at Target was on sale for 20% off last week. At the end of the week, a Target employee was asked to increase the price of the iPod by 20%. The employee adjusted the price back to what is was originally: $239. A manager walked by and told the employee that $239 was the incorrect price. Who is right?
Answer provided by our tutors
the start price: $239
last week on sale for 20% off: 239 - 0.20*239 = 0.80*239
the new price increased by 20%: 0.80*239 + 0.20*0.80*239 = 1.20*0.80*239 = $229.44
the manager is right.
