Q: Nancy wanted to make peanut butter cookies for a family gathering, but her cousin is allergic to peanuts. She decided to make almond butter cookies instead. A jar of almond butter costs three times the amount that a jar of peanut butter does. It takes half a jar to make a batch of cookies. A jar of peanut butter costs $3. How many dollars more does it cost per batch to make almond butter cookies instead of peanut butter cookies?
A: A jar of almond butter costs 3 * 3 = $9. It takes half a jar to make a batch of cookies, so it costs 9 / 2 = $4.50 to use almond butter. It costs 3 / 2 = $1.50 to use peanut butter. Thus, it costs 4.50 - 1.50 = $3 more to make a batch of almond butter cookies than peanut butter cookies. The answer is 3.
Question: Moses and Tiffany want to see who is faster. But instead of a race, they just start running down the block. Tiffany runs 6 blocks in 3 minutes. Moses runs 12 blocks in 8 minutes. What is the speed (defined as blocks per minute) of the runner with the higher average speed?
Answer: Tiffany runs 2 blocks per minute because 6 / 3 = 2. Moses runs 1.5 blocks per minute because 12 / 8 = 1.5. The runner with the highest average speed is Tiffany because 2 > 1.5. The answer is 2.
[Question]Ever since she was a little girl, Sheila has dreamed of traveling the world. To help fund her dream, she bought a large piggy bank in December and started saving. By last week, she had saved $3,000. Pleased with her progress, she has decided to continue saving $276 per month, for 4 years. Today, Sheila’s family secretly added $7,000 into the piggy bank. At the end of 4 years, how much money will be in Sheila’s piggy bank?
[Answer]Today, Sheila’s piggy bank has $3000 + $7000 = $10000. Sheila will be saving for 4 years which is equivalent to 12 months / year * 4 years = 48 months. In 4 years, she will save $276 / month * 48 months = $13248. The piggy bank will have a total of $10,000 + $13,248 = $23248. The answer is 23248.
Q: John reels in 3 crab baskets a week. Each basket holds 4 crabs. He collects crabs twice a week. Each crab sells for $3. How much money does he make?
A: He collects 3 * 4 = 12 crabs each time. He thus collects 12 * 2 = 24 crabs a week. So he makes 24 * 3 = $72 a week. The answer is 72.
Question: John is a door-to-door salesman. He visits 50 houses a day. 20% of them buy something from them. Of those that buy something half buy a $50 set of knives and the other half buy a $150 set of knives. How much does he sell a week when he works 5 days a week?
Answer: There are 50 * .2 = 10 houses buying from him per day. Of those 10 / 2 = 5 buy each type of knife set. So he gets 5 * 50 = $250 per day from the cheap set. He also gets 5 * 150 = $750 from the expensive set. So he makes a total of 250 + 750 = $1000 per day. That means he makes 1000 * 5 = $5000. The answer is 5000.
Q: Tina is working on her homework when she realizes she's having a hard time typing out her answers on her laptop because a lot of the keys are sticky. She is trying to get her homework done before dinner, though, so she needs to decide if she has time to clean her keyboard first. Tina knows her assignment will only take 10 minutes to complete. Dinner will be ready at 5:30 p.m. Tina decides to time how long it takes to remove and clean one key and will then multiply that time by how many keys she needs to fix. She counts 15 keys that are sticky and times it to take 3 minutes to clean one. After Tina has cleaned one key, there are 14 left to clean. How many minutes total will it take for Tina to both clean the remaining keys and finish her assignment?
A:
Tina has already cleaned one key so she has 14 left which take 3 minutes each to clean, 14 x 3 = 42 minutes to clean all the keyboard keys. Her assignment will take 10 minutes to complete, so she needs 42 minutes + 10 minutes = 52 minutes total before dinner. The answer is 52.
