Q: Preston has a sandwich shop. He charges $5 for each sandwich. He also charges $20 for a delivery fee. Abra Company orders 18 sandwiches from Preston and also tips him 10%. How much total, in dollars, did Preston receive?
A: First, find the price of the sandwiches $5 per sandwich * 18 sandwiches = $90. Now add in the delivery fee $90 + $20 = $110. Now the tip $110 * 0.10 = $11. Add the tip to the price of the sandwiches $110 + $11 = $121 in total. The answer is 121.
Question: Joseph wants to go to Boston for a road trip. If he takes route A, it will take him 5 hours to arrive; but if he takes route B, it will only take him 2 hours to arrive at his destination. How much time will he save if he takes route B to Boston and back to his home?
Answer: He will spend 5 x 2 = 10 hours if he takes route A. Meanwhile, he will spend 2 x 2 = 4 hours if he takes route B. Therefore, Joseph can save 10 - 4 = 6 hours if he takes route B both ways. The answer is 6.
[Question]A new factory opens up and hires 20 people to make t-shirts. Each person makes on average 20 shirts per day during their 8-hour shift. The employees each get paid $12 an hour plus $5 per shirt they make. The company sells shirts for $35 each.  Nonemployee expenses come out to $1000 a day. How much does the company make in profits per day?
[Answer]Each employee gets paid 20 * 5 = $100 for the shirts they make. They also get paid 12 * 8 = $96 for hours worked. So they get a total of 100 + 96 = $196 per day. That means employee cost is 20 * 196 = $3920. The factory makes 20 * 20 = 400 shirts. So they make 400 * 35 = $14,000 from selling shirts. So they made a profit of 14,000 - 3,920 - 1,000 = $9,080. The answer is 9080.
Q: If farmer Steven can use his tractor to plow up to 10 acres of farmland per day, or use the same tractor to mow up to 12 acres of grassland per day, how long would it take him to plow his 55 acres of farmland and mow his 30 acres of grassland?
A: At a rate of 10 acres per day, he can plow his 55 acres of farmland in 55 / 10 = 5.5 days. At a rate of 12 acres per day, he can mow his 30 acres of grassland in 30 / 12 = 2.5 days. Altogether, it would take him 5.5 + 2.5 = 8 days to completely mow and plow his land. The answer is 8.
