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

### Instruction:
Borris liquor store uses 90 kilograms of grapes every 6 months. He is thinking of increasing his production by twenty percent. How many grapes does he need in a year after increasing his production?

### Response:
 Kwa mwaka, Borris anatumia kilogramu 90 x 2 = <<90*2=180>>180 za zabibu kwa uzalishaji wake.
Anataka kuongeza hii kwa 20/100 x 180 = <<20/100*180=36>>36 kilogramu.
Hivyo, Borris anahitaji kilogramu 180 + 36 = <<180+36=216>>216 za zabibu kwa uzalishaji wake kwa mwaka.
