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

### Instruction:
Mia is buying Christmas gifts for her family. She has spent $30 on each of her 3 siblings, and the rest of her spending was for her parents. If Mia spent a total of $150 on Christmas gifts and each of her parents received gifts of equal value, how much money, in dollars, did she spend on each parent’s gift?

### Response:
 Mia alitumia jumla ya $30 kwa kila ndugu * ndugu 3 = $<<30*3=90>>90 kwa ndugu zake.
Hivyo, alitumia $150 matumizi yote - $90 matumizi kwa ndugu zake = $<<150-90=60>>60 kwa wazazi wake.
Kila mzazi alipokea kiasi sawa, hivyo zawadi ya kila mzazi iligharimu $60 matumizi yote kwa wazazi / 2 = $<<60/2=30>>30.
