Q: John decides to get a new phone number and it ends up being a recycled number. He used to get 20 text messages a day. Now he is getting 55. Assuming the number of texts his friends send has not changed, how many text messages per week is he getting that are not intended for him?
A: He is getting an extra 55 - 20 = 35 text messages per day. So he is getting an extra 35 * 7 = 245 text messages per week. The answer is 245.
Question: The teacher agrees to order pizza for the class. For every student in the class, she will buy 2 pieces of cheese and 1 piece of onion and they will eat exactly that amount. A large pizza has 18 slices. She orders 6 total pizzas and there are 8 pieces of cheese and 4 pieces of onion leftover. How many students are in the class?
Answer: Cheese pizzas are 2 / 3 of the pizza's purchased because 2 / (2 + 1) = 2 / 3. She buys 4 cheese pizzas because 6 x (2 / 3) = 4. These give her 72 pieces of cheese pizza because 4 x 18 = 72. The students at 64 pieces of cheese because 72 - 8 = 64. There are 32 students in her class because 64 / 2 = 32. The answer is 32.
[Question]Lana and Mike are taking their dog and renting a cabin in the mountains for 2 weeks. The daily rate is $125.00 There is a $100.00 pet fee. There is also a 20% service/cleaning fee for the rental. They need to pay 50% of the entire bill as a security deposit. How much is their security deposit?
[Answer]There are 7 days in a week and they're going for 2 weeks so that's 7 * 2 = 14 days. The daily rate is $125.00 and they are staying for 14 days so that's 125 * 14 = $1,750.00. There is also a $100.00 pet fee on top of their rental fee of $1,750.00 so that's 100 + 1750 = $1850.00. There is a 20% fee on the $1,850.00 so the fee comes to .20 * 1850 = $370.00. The rental will costs $1,850.00 and there is $370.00 service / cleaning fee for a total of 1850 + 370 = $2,220.00. They need to pay 50% of the entire bill as a security deposit so that will be .5 * 2220 = $1,110.00. The answer is 1110.
Q: At peak hours, 11 am - 1 pm and 5 pm - 6 pm, the local fast-food restaurant serves 12 cars every 15 minutes. Off-peak times, they serve 8 cars every 15 minutes. From 4 pm - 6 pm, how many customers do they serve?
A: 5 pm - 6 pm is one hour and they measure service in 15 - minute blocks so 60 / 15 = 4 15 min blocks. At peak times, they serve 12 cars every 15 minutes so they serve 12 * 4 = 48 cars in 60 minutes. Off peak times, 4pm - 5 pm, they serve 8 cars every 15 minutes so they serve 8 * 4 = 32 cars in 60 minutes. From 4pm - 5 pm they serve 32 cars and from 5pm - 6 pm they serve 48 cars so they serve 32 + 48 = 80 cars. The answer is 80.
Question: John gets a bonus that's the same percentage every year. Last year he made $100,000 and got a $10,000 bonus. This year he makes $200,000. How much will John make this year when adding both his total pay and bonus together?
Answer:
First we need to determine the bonus percentage, which is found by dividing the bonus amount by the amount John made for the year, taking 10,000 / 100,000 = .10, or 10 percent. Then, we take John's earnings from this year and multiply them by the same percentage, taking 200,000 * .1 = 20,000 dollars in bonuses. We then add these two numbers together, for a total of 200,000 + 20,000 = 220,000 dollars. The answer is 220000.
