Question: A bag of chips weighs 20 ounces, and a tin of cookies weighs 9 ounces. If Jasmine buys 6 bags of chips and 4 times as many tins of cookies, how many pounds does she have to carry?
Answer with step-by-step thinking: Jasmine's bags of chips weigh 20 * 6 = 120 ounces. Jasmine buys 6 * 4 = 24 tins of cookies. Jasmine's tins of cookies weigh 9 * 24 = 216 ounces. She has to carry 120 + 216 = 336 ounces. She has to carry 336 / 16 = 21 pounds.
So the answer is 21.

Question: Kevin's fish tank was leaking slowly at a rate of 1.5 ounces per hour. He planned to go to the fish tank store later that day to get a new tank, but it may be as long as 12 hours before he can return home with the new tank. Therefore, to collect the leaking fluid over that time, he placed a bucket underneath the tank that could hold twice the amount of fluid that would leak over 12 hours. What size bucket, in ounces, did he use?
Answer with step-by-step thinking: Over 12 hours, a leak of 1.5 ounces per hour for 12 hours would generate 1.5 * 12 = 18 ounces. A bucket that can hold twice the volume leaked is 18 * 2 = 36 ounces.
So the answer is 36.

Question: The balance of Pam's bank account tripled during the year. At the end of the year, Pam withdrew $250. If her current balance is $950, how much did she have in the bank account at the beginning of the year?
Answer with step-by-step thinking:
First, we have to come up with the balance before her withdrawal. $950 (current) + $250 (withdraw) = $1200. Now since we know that is triple, we divide by 3. $1200 / 3 = $400.
So the answer is 400.
