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? Give me reasons, before answering the question
Mia spent a total of $30 per siblings * 3 siblings = $90 on her siblings. She therefore spent $150 total spending - $90 spending on her siblings = $60 on her parents. As each parent received an equal amount, each parent's gift cost $60 total spending on parents / 2 = $30. So the final answer is 30.
