Question: Milo can roll downhill on his skateboard at twice the speed that he can run. And Milo's best friend, Cory, can drive his wheelchair at twice the speed that Milo can roll downhill on his skateboard. If Cory always drives his wheelchair at 12 miles per hour, how many miles can Milo run in two hours?
Answer: Since Cory drives his wheelchair at 12 miles per hour, then Milo rolls downhill on his skateboard at 12 / 2 = 6 miles per hour. Therefore, Milo runs at 6 / 2 = 3 miles per hour. If Milo runs for 2 hours at 3 miles per hour, then Milo will travel 2 * 3 = 6 miles. The answer is 6.

Question: Rebecca bought 2 pies for the holiday weekend. Each pie was sliced into 8 slices. Rebecca ate 1 slice of each pie. Her family and friends ate 50% of the remaining pies over the weekend. On Sunday evening Rebecca and her husband each had another slice of pie. How many slices are remaining?
Answer: She bought 2 pies that had 8 slices each for a total of 2 * 8 = 16 slices. Rebecca ate 2 of the 16 slices leaving 16 - 2 = 14 slices. Her family and friends at 50% of the pie so they ate 14 * .50 = 7 slices. There were 14 slices and her family and friends ate 7 slices so that leaves 14 - 7 = 7 slices. Sunday night Rebecca and her husband each had a slice from the remaining slices so that leaves 7 - 2 = 5 slices. The answer is 5.

Question: A store owner buys clothes wholesale and adds 80% to the wholesale price to set the retail price. The retail price of a pair of pants is $36. What is the wholesale price?
Answer:
Let X be the wholesale price. The retail price of a pair of pants is X + X * 80% = $36. Thus 1.8 * X = $36. Thus X = $36 / 1.8 = $20. The answer is 20.
