### Instruction:
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?

### Response:
She bought 2 pounds of bananas at $0.75 per pound so 2 *.75 = $<<2*0.75=1.50>>1.50
The milk cost $4.00 but was on sale for 1/2 off so 4 * .50 = $<<4*.50=2.00>>2.00
She had a $1.25 coupon for the laundry detergent so 10.25 - 1.25 = $<<10.25-1.25=9.00>>9.00
When you add everything up it comes to 1.50 + 2.00 + 3.50 + 9.00 = $<<1.50+2.00+3.50+9.00=16.00>>16.00
She paid with a $20.00 bill so 20 - 16 = $<<20-16=4.00>>4.00 left over
