[Question]In a classroom, there are blue chairs, green chairs, and white chairs. There are 10 blue chairs. The green chairs are 3 times as many as the blue chairs, and there are 13 fewer white chairs than the green and blue chairs combined. How many chairs are there in a classroom?
[Answer]There are 10 x 3 = 30 green chairs. The total number of blue and green chairs is 10 + 30 = 40. So, there are 40 - 13 = 27 white chairs. Therefore, there are 40 + 27 = 67 chairs in a classroom. The answer is 67.
Q: Bingo has two dogs. On average, they walk a total of 70 miles a week. The first dog walks an average of 2 miles a day. How many miles a day does the other dog average?
A: The first dog walks 14 miles in a week because 7 x 2 = 14. The second dog walks 56 miles in a week because 70 - 14 = 56. The second dog walks an average of 8 miles a day because 56 / 7 = 8. The answer is 8.
Question: The city is holding its annual rubber duck race for charity. The regular size rubber ducks are $3.00 each and the large size rubber duck is $5.00 each. All of the rubber ducks will be dropped into the river at the same time and the first duck that floats across the finish line wins. They sold 221 regular size ducks and 185 large size ducks. How much money did the city raise for charity?
Answer: They sold 221 regular size rubber ducks at $3.00 each so they made 221 * 3 = $663.00. They sold 185 large rubber ducks at $5.00 each so they made 185 * 5 = $925.00. The regular size ducks brought in $663.00 and the large brought in $925.00 for a total of 663 + 925 = $1,588.00 for charity. The answer is 1588.
[Question]John used to go to the gym multiple times a weak but because of lockdowns he hasn't been able to go. He used to lift 700 for squat, 400 for bench, and 800 for deadlift. For squat he lost 30% of his lift. He didn't lose any weight on bench because he was able to train that at home and he lost 200 pounds on deadlift. What is his new total?
[Answer]He lost 700 * .3 = 210 pounds on squat. So his squat is now 700 - 210 = 490 pounds. His deadlift is 800 - 200 = 600 pounds. So his total is now 490 + 600 + 400 = 1490 pounds. The answer is 1490.
Q: Three times as many children as adults attend a concert on Saturday. An adult ticket costs $7 and a child's ticket costs $3. The theater collected a total of $6,000. How many people bought tickets?
A: Let X be the number of adults attending the concert. The number of children attending the concert is 3 * X. The theater collected a total of 7 * X + 3 * (3 * X) = $6,000. Multiplying through the parentheses we get 7X + 9X = $6,000. Adding like terms we get 16X = $6,000. Dividing both sides by 16 we get X = 375, the number of adults attending the concert. The number of children attending the concert is triple this number: 375 adults * 3 children / adult = 1125 children. The number of people attending the concert is 375 + 1125 = 1500 people. The answer is 1500.
