[Question]: 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?
[Answer]: 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 answer is 30.

[Question]: Andrea buys herself a pony for her 30th birthday. She pays $500/month to rent a pasture for it, $10 a day for food, and $60/lesson for two lessons a week. How much does she spend on her pony in a year?
[Answer]: First find the annual cost of food: $10 / day * 365 days = $3650. Then find how much she spends a week on lessons: $60 / lesson * 2 lessons = $120. Then multiply that weekly cost by the number of weeks per year to find the annual cost: $120 / week * 52 weeks / year = $6240. Then find the annual cost of the pasture: $500 / month * 12 months / year = $6000. Then add all the costs to find the total cost: $6000 + $6240 + $3650 = $15890.
So the answer is 15890.
