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

### Instruction:
 Tony alilipa $7 kwa makundi 2 ya matofaa na kundi 1 la ndizi. Arnold alilipa $5 kwa kundi 1 la matofaa na kundi 1 la ndizi. Kundi moja la ndizi lina gharama kiasi gani?


### Response:
 Tony alilipa $7-$5= $<<7-5=2>>2 zaidi kuliko Arnold.
Tunajua alinunua idadi ile ile ya ndizi kama Arnold lakini alinunua makundi 2-1=1 ya matofaa zaidi kuliko Arnold.
Hivyo, kundi moja la matofaa linapaswa kuwa na gharama ya $2.
Kama Arnold alilipa $5 na $2 kwa kundi moja la matofaa, basi kundi moja la ndizi linagharimu $5-$2=$<<5-2=3>>3.
