Question: Megan works eight hours a day and earns $7.50 per hour. If she works 20 days a month, how much will be her total earnings for two months of work?
Answer: Step-by-step reasoning process: In a day, Megan earns 8 x $7.50 = $60. In a month, she will be earning 20 x $60 = $1200. Therefore, Megan will earn a total of 2 x $1200 = $2400 for two months of work.
So the answer is 2400.

Question: Oscar wants to train for a marathon. He plans to add 2/3 of a mile each week until he reaches a 20-mile run. How many weeks before the marathon should he start training if he has already run 2 miles?

Question: Five friends eat at a fast-food chain and order the following: 5 pieces of hamburger that cost $3 each; 4 sets of French fries that cost $1.20; 5 cups of soda that cost $0.5 each; and 1 platter of spaghetti that cost $2.7. How much will each of them pay if they will split the bill equally?
Answer: Step-by-step reasoning process: The cost of 5 pieces of hamburger is $3 x 5 = $15. The cost of 4 sets of French fries is $1.20 x 4 = $4.80. The cost of 5 cups of soda is $0.5 x 5 = $2.50. So their total bill is $15 + $4.80 + $2.50 + $2.7 = $25. Hence, each of the five friends will contribute $25 / 5 = $5.
So the answer is 5.
