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

### Instruction:
Tony paid $7 for 2 dozen apples and 1 bunch of bananas. Arnold paid $5 for 1 dozen apples and 1 bunch of bananas. How much does a bunch of bananas cost?

### 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.
