The milk cost $4.00 but was on sale for 1/2 off so 4*.50 = $<<4*.50=2.00>>2.00

She bought 2 pounds of bananas at $0.75 per pound so 2 *.75 = $<<2*0.75=1.50>>1.50

She had a $1.25 coupon off of laundry detergent so 10.25 - 1.25 = $<<10.25-1.25=9.00>>9.00

When you add all of her purchases together then 2 + 1.50 +3.50 + 9.00 = $<<2+1.50+3.50+9=16.00>>16.00

She paid with a $20 bill so 20-16 = $<<20-16=4>>4 left over

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?
