Question: A chair costs 1/7 of the cost of a table. If a table costs $140, how much will it cost to buy a table and 4 chairs?
Answer with step-by-step thinking: One chair costs $140 x 1 / 7 = $20. Four chairs cost $20 x 4 = $80. So a table and 4 chairs cost $140 + $80 = $220.
So the answer is 220.


Question: Madison takes her dog to the dog park. Counting Madison's dog, half the dogs have spots and 1/5 have pointy ears. If 15 dogs have spots, how many have pointy ears?
Answer with step-by-step thinking: First double the number of dogs with spots to find the total number of dogs: 15 dogs * 2 = 30 dogs. Then multiply that number by 1 / 5 to find the number that have pointy ears: 30 dogs * 1 / 5 = 6 dogs.
So the answer is 6.


Question: Kyle bikes for 2 hours to work every day. Ten times the time he takes to travel to work and back is the same as the cost of buying a pack of snacks (in dollars). How much will Ryan pay, in dollars, to buy 50 packs of snacks?
Answer with step-by-step thinking:
A round trip to work and back takes 2 * 2 = 4 hours. Ten times the time Kyle takes to travel to work and back is the same as the cost of buying a pack of snacks, meaning the packs are sold at 4 * 10 = $40 each. Ryan will pay $40 * 50 = $2000 to buy 50 packs of snacks?.
So the answer is 2000.
