Q: Chad is hosting a BBQ on the hottest day of the year, where there will be a total of 15 people. He will need 2 pounds of ice per person to account for the heat. One pound bags of ice are sold for $3.00 for a pack of 10. How much will he spend on ice?
A: He’s inviting 15 guests and will need 2 pounds per person so he will need 15 * 2 = 30 pounds of ice. Ice is sold in 10 - pound bags and he needs 30 pounds so he will need 30 / 10 = 3 bags of ice. Each bag is $3.00 and he needs 3 bags so they will cost 3 * 3 = $9.00. The answer is 9.
Question: Caleb, Andy and Billy went on a picnic with their father. Billy took 6 candies with him, Caleb took 11 and Andy left with 9. On the way, their father bought a packet of 36 candies. He gave 8 candies to Billy, 11 to Caleb and the rest to Andy. How many more candies does Andy now have than Caleb?
Answer: Billy took some candies and got more from his father for a total of 6 + 8 = 14 candies. Caleb has a total of 11 + 11 = 22 candies. Their father gave out 8 + 11 = 19 candies from a pack of 36. He gave the rest which is 36 - 19 = 17 candies to Andy. Andy has a total of 9 + 17 = 26 candies. Andy has 26 - 22 = 4 more candies than Caleb. The answer is 4.
[Question]A car is driving through a tunnel with many turns. After a while, the car must travel through a ring that requires a total of 4 right-hand turns. After the 1st turn, it travels 5 meters. After the 2nd turn, it travels 8 meters. After the 3rd turn, it travels a little further and at the 4th turn, it immediately exits the tunnel. If the car has driven a total of 23 meters around the ring, how far did it have to travel after the 3rd turn?
[Answer]From the details given, the car has traveled 5 meters at the 1st turn + 8 meters after the 2nd turn + 0 meters after the 4th turn = 13 meters around the ring. It must therefore have driven 23 total meters – 13 calculated meters = 10 meters after the 3rd turn. The answer is 10.
