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

### Instruction:
Fabian is shopping at a nearby supermarket. He wants to buy 5 kilograms of apples, 3 packs of sugar, and 500 grams of walnuts. One kilogram of apples costs $2, and one kilogram of walnuts costs $6. One pack of sugar is $1 cheaper than one kilogram of apples. How much Fabian needs to pay for the items he wants to buy?

### Response:
 Kilo 5 za ndizi inagharimu 5 * 2 = $<<5*2=10>>10.
Kwa gramu 500 za karanga, Fabian anapaswa kulipa 6 * 0.5 = $<<6*0.5=3>>3.
Pakiti moja ya sukari inagharimu 2 - 1 = $<<2-1=1>>1.
Hivyo Fabian atalipa 3 * 1 = $<<3*1=3>>3 kwa sukari.
Jumla Fabian anapaswa kulipa 10 + 3 + 3 = $<<10+3+3=16>>16.
