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

### Instruction:
The balance of Pam's bank account tripled during the year. At the end of the year, Pam withdrew $250. If her current balance is $950, how much did she have in the bank account at the beginning of the year?

### Response:
 Kwanza, tunapaswa kupata salio kabla ya kutoa pesa. $950 (sasa) + $250 (kutoa) = $<<950+250=1200>>1200.
Sasa tukijua kuwa ni mara tatu, tunagawanya kwa 3. $1200 / 3 = $<<1200/3=400>>400.
