Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### 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:
 Maziwa yaligharimu $4.00 lakini yalikuwa na punguzo la 1/2 hivyo 4 * 0.50 = $2.00
Josie alinunua kilo 2 za ndizi kwa $0.75 kwa kilo hivyo alitumia 2 * 0.75 = $1.50
Alipata kupon ya $1.25 punguzo kwenye sabuni ya kufulia hivyo 10.25 - 1.25 = $9.00
Ukiweka pamoja vitu vyote inakuwa 2 + 1.50 + 3.50 + 9 = $16.00
Alilipa kwa noti ya $20 hivyo 20 - 16 = $4 zilizobaki
