Annalise was sent by her mother to the store to buy 10 boxes of Kleenex Ultra Soft Facial Tissues. If each box has 20 packs of tissues and each pack contain 100 tissues sold at five cents each, calculate the total amount of money Annalise spent to buy the ten boxes. Let's be accurate as possible.
If a box of tissue has 20 packs of tissues, ten boxes have 20 packs / box * 10 boxes = 200 packs. Since each pack has 100 tissues, Annalise bought 100 tissues / pack * 200 packs = 20000 tissues. Annalise bought 20000 tissues at five cents each, at a total cost of 20000 tissues * $0.05 = $1000.
The answer: 1000.
