At Ken's local store, a pound of steak is going for $7. He decides to get two pounds. At the till, he pays using a $20 bill. How much money will he get back?
Let's think: 2 pounds of steak will cost Ken 2 * 7 = 14 dollars. Subtracting that amount from $20 will give 20 - 14 = 6 dollars. Ken will therefore get 6 dollars back.. The answer is: 6.

Pat is buying supplies for S'mores. He and his friends will each eat 3 S'mores. There are 8 of them in total. It costs $3 in supplies to make 4 S'mores. How much will it cost to buy all the supplies?
Let's think: They are making 24 S'mores because 8 x 3 = 24. Each S'more costs $.75 to make because 3 / 4 = .75. It will cost $18 to make them all because 24 x .75 = 18.. The answer is: 18.

Carla needs to bring water to her animals. Each horse needs twice as much water as a pig, and the chickens drink from one tank that needs 30 gallons. How many gallons of water does Carla need to bring if she has 8 pigs and 10 horses and each pig needs 3 gallons of water?
Let's think: First figure out how much water all the pigs need: 8 pigs * 3 gallons / pig = 24 gallons. Then figure out how much water one horse needs by multiplying a pig's needs by 2: 3 gallons * 2 = 6 gallons. Now find how much water all the horses need: 10 horses * 6 gallons / horse = 60 gallons. Finally, add up all the animals' water needs: 24 gallons + 60 gallons + 30 gallons = 114 gallons.. The answer is: 114.

Allyn is a golfer. At the starting tee, he hit the golf ball and it traveled 180 yards straight toward the hole. On his second turn, he hit the ball again straight toward the hole and it traveled half as far as it did on his first turn, but the ball landed 20 yards beyond the hole. On his third swing, he hit the ball onto the green and it rolled into the hole. What is the distance, in yards, from the starting tee to the hole?
Let's think:
On his second turn, the ball traveled 180 / 2 = 90 yards. After two turns, the ball had traveled 180 + 90 = 270 yards. Since, after the second turn, the ball was 20 yards past the hole, this means the distance from the starting tee to the hole was 270 - 20 = 250 yards.. The answer is: 250.
