Question: Sally took 342 pens to her class of 44 students. If she gave 7 pens to each student, left half of the remainder in her locker, and took the rest home, how many did she take home?
Answer: She gave 7 pens each to 44 students for a total of 7 * 44 = 308 pens. There are now 342 - 308 = 34 pens left. She left half of 34 pens in her locker which is 34 * (1 / 2) = 17 pens. She took 34 - 17 = 17 pens home. The answer is 17.
[Question]Nancy and Jason are learning to dance for the first time. Nancy steps on her partner's feet 3 times as often as Jason. If together they step on each other's feet 32 times, how many times does Jason step on his partner's feet?
[Answer]Let n be the number of times Nancy steps on her partner's feet and j be the number of times Jason does. We know that n = 3j and n + j = 32. Substituting the first equation into the second equation, we get 3j + j = 32. Combining like terms, we get 4j = 32. Dividing both sides by 4, we get j = 8. The answer is 8.
Q: Toby's father gave him $343 for passing the test. Toby decided to share it with his two brothers, so he gave each of them 1/7 of $343. How many dollars are left for Toby?
A: Toby gave each of his brothers 1 / 7 * $343 = $49. Toby gave his 2 brothers a total of 2 * $49 = $98. So, Toby now has $343 $98 = $245. The answer is 245.
Question: It takes 5 people to lift a car and twice as many people to lift a truck. How many people are needed to lift 6 cars and 3 trucks?
Answer: It takes 5 x 2 = 10 people to lift a truck. 5 x 6 = 30 people are needed to lift the cars. 10 x 3 = 30 people are needed to lift the trucks. Altogether, 30 + 30 = 60 people are needed. The answer is 60.
[Question]Linda is repainting her bedroom. The wall area is 600 sq. ft. If a gallon of paint can cover 400 sq. ft., how many gallon cans of paint will Linda have to buy if she wants to do two coats?
[Answer]Linda wants to do two coats, so the total area she will be painting is 2 coats * 600 sq. ft. / coat = 1200 sq. ft. A gallon of paint will cover 400 sq. ft., so Linda will need 1200 sq. ft. / 400 sq. ft. per can = 3 cans of paint. The answer is 3.
[Question]Isabel loves to run in the forest and she does it within a circuit that is 365 meters long. She runs the circuit 7 times in the morning and runs it 3 times in the afternoon. How many meters does Isabel run during a week?
