Anna went to Old Navy to buy clothes for back to school. As she was in the checkout line she noticed that the store was having a sale in which each customer receives either a 10% discount on a purchase under $75, or 15% discount on purchases over $75. When Anna gets to the checkout stand her total comes out to $71.48. She decides to buy the fewest bags of skittles so that she can reach the $75 minimum to receive the bigger discount. The price of each bag of skittles is $1.29. First, find out how many bags of skittles Anna needs to purchase to reach the $75 minimum. Then determine if it is a better deal to buy the skittles and get the bigger discount, or not buy the skittles and get the smaller discount and determine how much money Anna would save using one discount over the other.
