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

### Instruction:
Mike is shopping at the mall. He needs to buy a shirt, a new wallet, and some food for the evening. The shirt costs a third of the value of the wallet. The wallet is $60 more than the cost of the food, on which Mike spent $30. How much did Mike spend that day on the shopping?

### Response:
 Mkoba una gharama ya $60 zaidi ya chakula, hivyo ni $30 + $60 = $<<30+60=90>>90.
Shati ni theluthi ya gharama ya mkoba, hivyo ni $90 / 3 = $<<90/3=30>>30.
Jumla ya Mike alitumia siku hiyo ni $30 + $30 + $90 = $<<30+30+90=150>>150.
