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

### Instruction:
Lauren wanted to make burgers and fries for dinner.  She needed a few things from the grocery store and bought the following:  2 pounds of hamburger meat that was on sale for $3.50 a pound.  1 pack of hamburger buns for $1.50.  A head of lettuce for $1.00 and a large 1.5-pound tomato that was priced at $2.00 per pound.  She also needed a jar of pickles that cost $2.50 and she had a $1.00 off coupon for that item.  How much change would Lauren get back if she paid with a $20 bill?

### Response:
 Alichukua nyama ya hamburger paundi 2 kwa $3.50 kwa paundi hivyo 2*3.50 = $<<2*3.50=7.00>>7.00
Nyanya ilikuwa na uzito wa paundi 1.5 na iligharimu $2.00 kwa paundi hivyo 1.5*2 = $<<1.5*2=3.00>>3.00
Ukihesabu vitu vyote alivyonunua alitumia 7+1.5+1+3+2.5 = $<<7+1.5+1+3+2.5=15.00>>15.00
Vitu vyake viligharimu $15.00 na alikuwa na kodi ya punguzo la $1.00 kwa matango hivyo 15-1 = $<<15-1=14.00>>14.00
Alikulipa na noti ya $20.00 hivyo 20-14 = $<<20-14=6.00>>6.00
