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

### Instruction:
Samuel is going to the cinema with his brother, Kevin. They both have a total budget of $20 for their outing. Samuel buys his $14 ticket, then spends $6 on drinks and food. Kevin buys his ticket, then spends $2 on drinks. They have both used their entire budget. How much did Kevin spend on food?

### Response:
 Tunajua Kevin alinunua tiketi na vinywaji, na hii ilimgharimu dola 14 + 2 = <<14+2=16>>16
Kwa kuwa Kevin alitumia bajeti yake yote, chakula chake lazima kigharimu dola 20 – 16 = <<20-16=4>>4
