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

### Instruction:
Mandy’s phone data plan charges $30 per month for data. Her first month, she got a promotional rate of one-third the normal price. However, in the fourth month she went over her data limit and was charged an extra fee of $15. How much did Mandy pay in the first 6 months for data?

### Response:
 Mandy alilipa 1/3 * 30 = 30 / 3 = $<<30/3=10>>10 kwa mwezi wake wa kwanza wa data.
Aliulipa 30 + 15 = $<<30+15=45>>45 kwa mwezi wake wa nne wa data.
Kwa kutoa miezi hiyo miwili, ana miezi 6 - 2 = <<6-2=4>>4 ya malipo ya kawaida.
Hivyo, Mandy alilipa 4 * 30 + 10 + 45 = 120 + 55 = $175 kwa miezi 6 ya kwanza kwa data.
