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.

Question: The price of buying a wooden toy at the new Craftee And Best store is $20, and the cost of buying a hat is $10. If Kendra went to the shop with a $100 bill and bought two wooden toys and three hats, calculate the change she received.
Answer: Step-by-step reasoning process: When Kendra bought 2 toys, she paid 2 * $20 = $40. Since the price of a hat is $10, when Kendra bought 3 hats, she paid 3 * $10 = $30. The total costs for the hats and wooden toys Kendra bought is $40 + $30 = $70. From the $100 bill, Kendra received change worth $100 - $70 = $30.
So the answer is 30.

Question: Rachel is stuffing envelopes. She has eight hours to complete the task, and there are 1,500 envelopes. In the first hour, Rachel stuffs 135 envelopes. The second hour she stuffs 141 envelopes. How many envelopes will Rachel need to stuff per hour to finish the job?
Answer: Step-by-step reasoning process: Rachel has 1500 - 135 - 141 envelopes = 1224 envelopes remaining to stuff. Rachel has 8 hours - 2 hours = 6 hours left to finish the task. Rachel needs to stuff 1224 envelopes / 6 hours = 204 envelopes per hour.
