[Question]Mr. Finnegan has 3 tanks with a capacity of 7000 gallons, 5000 gallons, and 3000 gallons, respectively. If he fills the first tank up to 3/4 full, the second tank with water up to 4/5 of its capacity, and the third tank up to half of its capacity, how many gallons in total are in the tanks?
[Answer]The capacity of the first tank is 7000 gallons, and if it is filled up to 3 / 4 full, it carries 3 / 4 * 7000 = 5250 gallons. When the second tank is filled up to 4 / 5 of its capacity, it carries 4 / 5 * 5000 = 4000 gallons. The total amount of water in the first two tanks is 5250 + 4000 = 9250 gallons. If Mr. Finnegan fills the third tank with water up to half its capacity, the tank fills up with 1 / 2 * 3000 = 1500 gallons. In total, the three tanks have 9350 + 1500 = 10850 gallons of water. The answer is 10850.
Q: A building has 10 floors. It takes 15 seconds to go up the stairs to the even-numbered floors and 9 seconds to go up to the odd-numbered floors. This includes getting to the first floor. How many minutes does it take to get to the 10th floor?
A: So for all even - numbered floors (2, 4, 6, 8, 10), it takes 5 * 15 = 75 seconds. And for all odd - numbered floors (1, 3, 5, 7, 9) it takes 5 * 9 = 45 seconds. To climb all the floors, it takes 75 + 45 = 120 seconds. So it takes 120 / 60 = 2 minutes to get to the 10th floor. The answer is 2.
Question: John's hair grows 1.5 inches every month. Every time it gets to 9 inches long he cuts it down to 6 inches. A haircut costs $45 and he gives a 20% tip. How much does he spend on haircuts a year?
Answer: He cuts off 9 - 6 = 3 inches when he gets a haircut. That means he needs to cut it every 3 / 1.5 = 2 months. So he gets 12 / 2 = 6 haircuts a year. He gives a 45 * .2 = $9 tip. So that means each hair cut cost 45 + 9 = $54. So he pays 54 * 6 = $324 a year. The answer is 324.
[Question]Betty has a tray of cookies and a tray of brownies. She has a real sweet tooth and eats 3 cookies a day and 1 brownie a day. If she starts with 60 cookies and 10 brownies, how many more cookies than brownies does she have after a week of eating like this?
[Answer]First we find how many cookies Betty will eat in a week by multiplying her daily amount by 7, meaning 7 * 3 = 21 cookies eaten in a week. We repeat this for the brownies, finding she eats 7 * 1 = 7 brownies in a week. We subtract the 21 cookies from the original amount of 60, finding 60 - 21 = 39 cookies remaining. We repeat this step for the brownies, finding 10 - 7 = 3 brownies remaining. In the end, therefore, Betty has 39 - 3 = 36 more cookies than brownies. The answer is 36.
Q: An NGO contracted a construction company to build 2000 houses within one year. In the first half of the year, they built the first 3/5 units of the contracted number. Due to unavoidable circumstances, the company could only build an additional 300 units by October. How many units remain from the contracted number that the company is supposed to build?
A: In the first half of the year, the company constructed 3 / 5 * 2000 = 1200 units. The number of units remaining to be built after the company built 1200 units in the first half of the year is 2000 - 1200 = 800. By October, the company built an additional 300 units, thus remaining with 800 - 300 = 500 units to be built. The answer is 500.
Question: Hayden works for a limousine company as a driver. He gets reimbursed for any gas he puts in the limo, his hourly wage is $15, and he gets paid an additional $5 for every ride he gives. A positive review from a rider in his limo also gets him a $20 bonus. Today, he gave rides to three groups, drove for eight hours, and had to put 17 gallons of gas at $3 per gallon in the limo to refill the tank. He got two good reviews. How many dollars is he owed for his work today?
Answer:
Hayden gave 3 groups rides, so he is owed 3 * 5 = $15. He drove for 8 hours, so he is owed 15 * 8 = $120. He refilled the gas tank, so he is owed back 17 * 3 = $51. He got two good reviews for a bonus of 2 * 20 = $40. Hayden is owned 15 + 120 + 51 + 40 = $226 for his work today. The answer is 226.
