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

### Instruction:
Barbara went shopping in a supermarket. She bought 5 packs of tuna for $2 each and 4 bottles of water for $1.5 each. In total, she paid $56 for her shopping. How much did Barbara spend on different than the mentioned goods?

### Response:
 Kwa samaki aina ya tuna Barbara alihitaji kulipa 5 * 2 = $<<5*2=10>>10.
Kwa chupa nne za maji, alihitaji kulipa 4 * 1.5 = $<<4*1.5=6>>6.
Alinunua kitu kingine pia, kwa sababu 56 = 10 + 6 + vitu tofauti.
Vitu tofauti Barbara alinunua kwa 56 - 10 - 6 = $<<56-10-6=40>>40.
