Question: Annie goes to school. Today is her birthday, so Annie decided to buy some sweets for her colleagues. Every classmate got 2 candies. In the end, Annie got left with 12 candies. If there are 35 people in Annie's class in total, how much did Annie spend on candies, if one candy costs $0.1?
Answer: There are 35 people in Annie's class, which means, she has 35 - 1 = 34 classmates. Every classmate got 2 candies, so in total Annie gave out 34 * 2 = 68 candies. In the beginning she had 68 + 12 = 80 candies. One candy costs $0.1, so Annie spend 80 * 0.1 = $8 on candies. The answer is 8.
[Question]Rockefeller Army Base has 3000 more than twice as many guns as Grenada Army Base, 400 less than thrice as many war tractors as Grenada Army Base, and 30 times as many soldier uniforms as Grenada Army Base reserved for its national protection. How many total war supplies does Rockefeller have if Grenada's war supplies are equally divided among the 6000 war supplies they have in total?
[Answer]For each component, Grenada Army Base has 6000 / 3 = 2000 each of guns, war tractors, and soldier uniforms. Rockefeller Army Base has 3000 + 2 * 2000 = 7000 guns. Rockefeller Army Base has 3 * 2000 - 400 = 5600 war tractors. Rockefeller Army Base has 30 * 2000 = 60000 soldier uniforms. The total war supplies Rockefeller Army Base has reserved are 60000 + 5600 + 7000 = 72600 war supplies for its national protection. The answer is 72600.
Q: It takes 320 rose petals to make an ounce of perfume. If each rose produces 8 petals, and there are 12 roses per bush, how many bushes will Fern have to harvest to make 20 12-ounce bottles of perfume?
A: First find the number of roses needed for one ounce of perfume: 320 petals / 8 petals / rose = 40 roses. Then multiply the number of roses needed for one ounce by the number of ounces per bottle to find the number of roses per bottle: 40 roses / ounce * 12 ounces / bottle = 480 roses / bottle. Then multiply that number by the number of bottles to find the total number of roses needed: 480 roses / bottle * 20 bottles = 9600 roses. Then divide that number by the number of roses per bush to find the number of bushes Fern needs to harvest: 9600 roses / 12 roses / bush = 800 bushes. The answer is 800.
Question: Clementine, Jake, and Tory make cookies for the school bake sale. Clementine baked 72 cookies. Jake baked twice as many cookies as Clementine. Tory baked half as many cookies as Jake and Clementine combined. They sell their cookies for $2 each. If they sell all their cookies, how much money do they make?
Answer: Clementine baked 72 cookies. Jake baked 72 x 2 = 144 cookies. Tory baked 216 / 2 = 108 cookies. Together they baked 72 + 144 + 108 = 324 cookies. They raised 324 x 2 = $ 648. The answer is 648.
[Question]At a party, there are 400 students, a combination of poets, singers and tree huggers. There are 50 more poets than treehuggers at the party. If the number of tree huggers is 120, how many singers are at the party?
[Answer]Since there are 50 more poets than treehuggers at the party, the number of poets is 120 + 50 = 170. The number of poets and tree huggers at the party is 170 + 120 = 290. Since the number of attendees at the party also included singers, there are 400 - 290 = 110 singers. The answer is 110.
[Question]A group of six friends planned to buy a car. The cost of the car is $1700 and they plan to share the cost equally. They had a car wash to help raise funds, which would be taken out of the total cost. The remaining cost would be split between the six friends. At the car wash, they earn $500. However, Brad decided not to join in the purchase of the car. How much more does each friend have to pay now that Brad isn't participating?
[Answer]
Start by finding the total that is left, $1700 car price - $500 earned at car wash = $1200 remaining. So the six friends should pay $1200 / 6 people = $200 each. Since Brad is not joining, then the 5 friends have to split Brad's share which is $200 / 5 = $40 each. The answer is 40.
