[Question]Ral is twice as old as Suri. In 3 years, Suri's current age will be 16. What is Ral's current age?
[Answer]If Suri will be 16 in 3 years, that means she is 16 - 3 = 13 years old now. Rai is twice as old as Suri, so she is 2 * 13 = 26 years old now. The answer is 26.
Q: Brady worked 6 hours every day in April. He worked 5 hours every day in June and 8 hours every day in September. What is the average amount of hours that Brady worked per month in those 3 months?
A: April = 6 * 30 = 180 hours. June = 5 * 30 = 150 hours. September = 8 * 30 = 240 hours. Total hours = 180 + 150 + 240 = 570 hours. 570 hours / 3 = 190 hours. He averaged working 190 hours per month. The answer is 190.
Question: Carlos bought a box of 50 chocolates. 3 of them were caramels and twice as many were nougats. The number of truffles was equal to the number of caramels plus 6. The rest of the chocolates were peanut clusters. If Carlos picks a chocolate at random, what is the percentage chance it will be a peanut cluster?
Answer: First find the number of nougats by doubling the number of caramels: 3 caramels * 2 nougats / caramel = 6 nougats. Then find the number of truffles by adding 7 to the number of caramels: 3 caramels + 6 = 9 truffles. Then find the number of peanut clusters by subtracting the number of each other chocolate from the total number of chocolates: 50 chocolates - 3 caramels - 6 nougats - 9 truffles = 32 peanut clusters. Finally, divide the number of peanut clusters by the total number of chocolates and multiply by 100% to find the percentage chance he gets a peanut cluster: 32 peanut clusters / 50 chocolates * 100% = 64%. The answer is 64.
[Question]Katy makes some brownies to eat throughout the week. She eats 5 on Monday and twice as many on Tuesday. After she has eaten the brownies on Tuesday, all of the brownies she made are gone. How many brownies did Katy make?
[Answer]On Tuesday, Katy ate 5 brownies * 2 = 10 brownies. As she has eaten all of the brownies she made, she must have made 5 Monday brownies + 10 Tuesday brownies = 15 brownies. The answer is 15.
Q: At Roosevelt high school there are 600 students in the senior class. A fifth of the students are in the marching band. Of the students in the marching band, half of them play a brass instrument. Of the students that play a brass instrument, a fifth of them play the saxophone. Of the students that play the saxophone, a third of them play the alto saxophone. How many students play the alto saxophone?
A: The number of students in the marching band is 600 / 5 = 120 students. The number of students that play a brass instrument is 120 / 2 = 60 students. The number of students that play the saxophone is 60 / 5 = 12 students. The number of students that play the alto saxophone is 12 / 3 = 4 students. The answer is 4.
Question: Marissa is serving her kids lunch. Each kid gets a burger with 400 calories and 5 carrot sticks with 20 calories each, and some cookies with 50 calories each. Marissa wants each kid to eat a total of 750 calories for lunch. How many cookies does each kid get?
Answer:
First figure out how many total calories come from the carrots by multiplying the calories per carrot by the number of carrots: 20 calories / carrot * 5 carrots = 100 calories. Then subtract the calories the kids have already eaten from the goal number of calories to find out how many more total calories they should eat: 750 calories - 400 calories - 100 calories = 250 calories. Then divide the total number of calories by the calories per cookie to find the number of cookies each kid gets: 250 calories / 50 calories / cookie = 5 cookies. The answer is 5.
