Q: Cilia wants to buy a multi-level dumbbell system. The first pair of dumbbells are 3 lb weights, the second pair is 5 lb weights and the third is 8 lb pounds. How much does the entire system weigh?
A: The first pair of weights weighs 3 lb each so all total they weigh 2 * 3 = 6 lbs. The second pair of weights weigh 5 lbs each so they weigh 2 * 5 = 10 lbs. The third pair of weights weigh 8 lbs each so they weigh 2 * 8 = 16lbs. All total, the entire system of weights weigh 6 + 10 + 16 = 32 lbs. The answer is 32.
Question: John paints a giant mural that is 6m by 3m. The paint costs $4 per square meter. The artist can paint 1.5 square meters per hour and charges $10 per hour. How much does the mural cost?
Answer: The mural is 6 * 3 = 18 sq meters. So the paint cost 18 * 4 = $72. The artist works for 18 / 1.5 = 12 hours. He charges 12 * 10 = $120. So the total cost is 120 + 72 = $192. The answer is 192.
[Question]John climbs up 3 flights of stairs. Each flight is 10 feet. He then climbs a rope that is half that height. Finally, he climbs a ladder that is 10 feet longer than the rope. How high up did he go?
[Answer]He climbed 3 * 10 = 30 feet of stairs. He then climbed 30 / 2 = 15 feet of rope. Finally, he climbed a 15 + 10 = 25 foot ladder. So in total, he climbed 30 + 15 + 25 = 70 feet. The answer is 70.
Q: A group of 30 tourists sets out on a walking tour of the rainforest. Two tourists are eaten by anacondas, then half the remaining tourists try to pet poisonous dart frogs and get poisoned. If only 1/7 of the poisoned tourists recovered, how many tourists are left at the end of the tour?
A: First, subtract the two tourists the anacondas got from the initial 30 tourists: 30 - 2 = 28. Next, divide 28 by two to find out how many tourists got poisoned: 28 / 2 = 14. Now figure out how many of the 14 poisoned tourists recovered: 14 / 7 = 2. The total number of surviving tourists is 14 + 2 = 16. The answer is 16.
Question: Ten more than twice the number of birds on the fence is 50. How many birds are on the fence?
Answer: Let x be the number of birds on the fence. We know that 10 + 2 * x = 50. Subtracting 10 from both sides, we get 2 * x = 50 - 10 = 40. Dividing both sides by 2, we get x = 20. The answer is 20.
Q: There were 50 racers in a bicycle charity race at the beginning of the race. After 20 minutes, 30 more racers joined the race. The total number of racers doubled after another 30 minutes. If at the end of the race only 130 people finished the race, what's the total number of people who dropped before finishing the race?
A:
At the start, there were 50 racers, who were joined by 30 more racers, thus 50 + 30 = 80 racers. After 30 more minutes, the number of racers doubled, totaling 80 * 2 = 160 racers. If the number of racers who finished is 130, the 160 - 130 = 30 racers dropped before finishing. The answer is 30.
