Isabella and Alexis went to the mall to buy some pants and dresses. Alexis bought 3 times more pants and dresses than Isabella. If Alexis bought 21 pairs of pants and 18 dresses, how many pairs of pants and dresses did Isabella buy in total?
Let's think: The number of pants Isabella bought is 21 / 3 = 7 pairs of pants. The number of dresses Isabella bought is 18 / 3 = 6 dresses. The total number of pants and dresses Isabella bought is 7 + 6 = 13.. The answer is: 13.

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?
Let's think: 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.

Bogan laid out 10 maggots for her pet beetle. The beetle only ate 1 and Bogan had to throw out the rest. Later that day, she tried feeding again and the beetle ate 3. If Bogan served 20 maggots in total, how many did she attempt to feed the beetle the second time?
Let's think: Bogan served a total of 20 maggots. Bogan gave the beetles 10 maggots in the first feeding. Bogan gave the beetles 20 - 10 = 10 maggots in the second feeding.. The answer is: 10.

Jeff spends three times as many hours on the weekend catching up with his Facebook pals as he does working. Monday through Friday, however, he spends four times as many hours working as he does catching up. If he spends 3 hours every day catching up, how many hours does he spend working in an entire week?
Let's think:
On the weekend, Jeff works 3 / 3 = 1 hour each day. On the weekdays, he spends 4 * 3 = 12 hours working each day. Thus, he spends 2 * 1 + 5 * 12 = 62 hours working each week.. The answer is: 62.
