Q: Nate got lost looking for his car in the airport parking lot. He had to walk through every row in Section G and Section H to find it. Section G has 15 rows that each hold 10 cars. Section H has 20 rows that each hold 9 cars. If Nate can walk past 11 cars per minute, how many minutes did he spend searching the parking lot?
A: First find the number of cars in Section G by multiplying the number of rows by the number of cars per row: 15 rows * 10 cars / row = 150 cars. Then do the same thing for Section H: 20 rows * 9 cars / row = 180 cars. Then add the two quantities of cars to find the total number of cars Nate walked past: 150 cars + 180 cars = 330 cars. Finally, divide the number of cars Nate passed by the numbers he passes each minute to find how long he spent searching: 330 cars / 11 cars / minute = 30 minutes. The answer is 30.
Question: 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?
Answer: 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]Debbie works at a post office packing boxes to mail. Each large box takes 4 feet of packing tape to seal, each medium box takes 2 feet of packing tape to seal, and each small box takes 1 foot of packing tape to seal. Each box also takes 1 foot of packing tape to stick the address label on. Debbie packed two large boxes, eight medium boxes, and five small boxes this afternoon. How much tape did she use?
[Answer]Debbie used 4 * 2 = 8 feet of tape for the large boxes. She used 2 * 8 = 16 feet of tape for the medium boxes. She used 1 * 5 = 5 feet of tape for the small boxes. There were 2 + 8 + 5 = 15 boxes in all. She used 1 * 15 = 15 feet of tape for the address labels. Thus, she used 8 + 16 + 5 + 15 = 44 feet of tape in all. The answer is 44.
Q: Mike is building a bridge out of LEGO blocks. To be successful he needs at least 40 bricks of type A, and half that many of type B. In total, he needs to use 150 bricks. How many bricks of other types than mentioned is he going to use?
A: Mike is using 40 blocks / 2 = 20 blocks of type B. He uses in total 40 blocks + 20 blocks = 60 blocks of type A and B. So he is going to use 150 blocks - 60 blocks = 90 blocks of other types. The answer is 90.
Question: Walter works 5 days a week in a fast-food chain and earns $5 per hour. Since he is a working student, he can only work 4 hours a day and allocates 3/4 of his weekly earning for his schooling. How much does he allocate for school?
Answer:
Walter's daily earning is $5 x 4 = $20. So he earns $20 x 5 = $100 per week. Therefore, he allocates $100 x 3 / 4 = $75 for his school. The answer is 75.
