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

### Instruction:
A car manufacturing company that produces 100 cars per month wants to increase its production to reach 1800 cars per year. How many cars should the company add to the monthly production rate to reach that target?

### Response:
 Acha Y iwe idadi ya magari yanayohitajika kuongezwa kwenye uzalishaji wa kila mwezi wa sasa.
Kisha ((100 + Y) * 12) = 1800.
Hivyo 1200 + 12 * Y = 1800.
12 * Y = 1800 - 1200 = 600
Y = 600 / 12 = <<600/12=50>>50
