[Question]A bag contains 50 fewer baseball cards than football cards. There are 4 times as many football cards as hockey cards. If there are 200 hockey cards in the bag, how many cards are there altogether?
[Answer]If there are 200 hockey cards in the bag and 4 times as many football cards as hockey cards, there are 4 * 200 = 800 football cards. The total number of football and hockey cards in the bag is 800 + 200 = 1000 cards. The bag contains 50 fewer baseball cards than football cards, meaning there are 800 - 50 = 750 baseball cards. Altogether, there are 750 + 1000 = 1750 cards. The answer is 1750.

Question: Mike is saving up to buy a house. He puts away 10% of his $150,000 a year salary. He needs to save up 20% of the cost of a $450,000 house for a downpayment. How long will it take?
