<human>:  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?
<bot>: How much did Mia spend on her siblings? ** Mia spent a total of $30 per siblings * 3 siblings = $<<30*3=90>>90 on her siblings.
How much did Mia spend on her parents? ** She therefore spent $150 total spending - $90 spending on her siblings = $<<150-90=60>>60 on her parents.
How much did each parent’s gift cost? ** As each parent received an equal amount, each parent’s gift cost $60 total spending on parents / 2 = $<<60/2=30>>30.
