Josie's mom gave her a $20 bill and asked her to go to the store for a few items. The list included a carton of milk for $4.00, a loaf of bread for $3.50, a box of laundry detergent for $10.25 and 2 pounds of bananas that were $0.75 per pound. Her mom also gave her a coupon for $1.25 off of the laundry detergent. At checkout, the clerk told her the milk was 1/2 off today. How much money did Josie have left over after she bought all of the groceries?
Thoughts? Step-by-step reasoning:
User
The milk cost $4.00 but was on sale for 1 / 2 off so 4 * .50 = $2.00. She bought 2 pounds of bananas at $0.75 per pound so 2 * .75 = $1.50. She had a $1.25 coupon off of laundry detergent so 10.25 - 1.25 = $9.00. When you add all of her purchases together then 2 + 1.50 + 3.50 + 9.00 = $16.00. She paid with a $20 bill so 20 - 16 = $4 left over.
Thus, the answer is 4.
