Question: There are 80 men in a race. 1/4 of the men tripped and were unable to finish. 2/3 of the remaining men were dehydrated and 1/5 of those dehydrated men couldn't finish the race. How many men finished the race?
Answer: 1 / 4 of 80 men is 80 / 4 = 20 men. 20 men couldn't finish, so 80 - 20 = 60 men remain. 60 * 2 / 3 = 40 men were dehydrated. 1 / 5 of the dehydrated couldn't finish 40 * 1 / 5 = 8 men. 60 - 8 = 52 men finished the race. The answer is 52.
[Question]In a grocery store, Julia bought 2 pieces of Snickers and 3 packs of M&M's. If each piece of Snickers costs $1.5 and a pack of M&M's has the same cost as 2 Snickers, how much is Julia's change if she gave the cashier 2 $10 bills?
[Answer]Two pieces of snickers cost $1.5 x 2 = $3. One pack of M&M's costs $3 so 3 packs cost $3 x 3 = $9. The total amount that she needs to pay is $3 + $9 = $12. Julia gave the cashier $10 x 2 = $20. So, her change is $20 - $12 = $8. The answer is 8.
Q: Orlan gave one-fourth of his 20-meter rope to Allan. He then gave two-thirds of the remaining to Jack. How many meters of rope is left to Orlan?
A: Orlan gave Allan 20 x 1 / 4 = 5 meters of rope. So he had 20 - 5 = 15 meters left. Then he gave 15 x 2 / 3 = 10 meters of the rope to Jack. Therefore, Orlan is left with 15 - 10 = 5 meters of rope. The answer is 5.
Question: Roselyn gives Mara three times as many books as she gives Rebecca and remains with 60 books. If Rebecca received 40 books, how many books did Roselyn have before?
Answer: If Roselyn gave Rebecca 40 books, and Mara was given three times as many books, Mara has 3 * 40 = 120 books. Rebecca and Mara's total number of books is 120 + 40 = 160 books. If Roselyn gave Mara and Rebecca her books, which is 160, then she initially had 60 + 160 = 220 books. The answer is 220.
[Question]The recipe for a four-person cake requires 2 eggs and 4 cups of milk. Tyler wants to use this recipe to make a cake for eight people. If Tyler has 3 eggs in the fridge, how many more eggs does Tyler need to buy?
[Answer]A cake for eight people would require 8 / 4 = 2 times as many eggs as a 4 people cake. If a 4 - person cake requires 2 eggs, then an 8 - person cake requires 2 x 2 = 4 eggs. Tyler needs to buy 4 - 3 = 1 more egg. The answer is 1.
[Question]Austin bought his seven friends each a robot. Each robot costs $8.75. He was charged $7.22 total for tax. He left with $11.53 in change. How much did Austin start with?
[Answer]
First we need to find the total amount for the robots. 7 robots * $8.75 per robot = $61.25 in total. Now we need to add in the tax $61.25 for the robots + $7.22 for tax = $68.47 total spent in store. Now to find what was the beginning amount we take the $68.47 total spent in - store + $11.53 in change = $80 to start. The answer is 80.
