[Question]Bridge and Sarah have $3 between them. If Bridget has 50 cents more than Sarah, how many cents does Sarah have?
[Answer]Let X be the amount of money Sarah has, so Bridget has X + 50 cents. We know that Sarah and Bridget combined have $3, or 300 cents, so X + X + 50 = 300. We therefore know that 2X = 250. So Sarah has 250 / 2 = 125 cents. The answer is 125.
Q: Henry drinks 15 bottles of kombucha every month. Each bottle costs $3.00 and is eligible for a cash refund of $0.10 per bottle when he takes it to a recycling center. After 1 year, how many bottles of kombucha will he be able to buy after he receives his cash refund?
