Q: At a flea market, Hillary sells handmade crafts for 12 dollars per craft. Today, Hillary sells 3 crafts and is given an extra 7 dollars from an appreciative customer. Later on, Hillary deposits 18 dollars from today's profits into her bank account. How many dollars is Hillary left with after making the deposit?
A: Hillary sells 3 crafts for 12 dollars each, for a total of 3 crafts * $12 / craft = $36. She receives an extra 7 dollars from a customer, increasing the total to $36 + $7 = $43. She then deposits 18 dollars in the bank, leaving her with $43 - $18 = $25. The answer is 25.

Q: Chris is trying to sell his car for $5200 and has gotten two price offers. One buyer offered to pay the full price if Chris would pay for the car maintenance inspection, which cost a tenth of Chris’s asking price. The other buyer agreed to pay the price if Chris replaced the headlights for $80 and the tires for three times as much. What is the difference between the amounts Chris will earn from the two offers?
A: Chris would earn 5200 - 5200 / 10 = 5200 - 520 = $4680 from the first buyer. He would earn 5200 - 80 - 80 * 3 = 5200 - 80 * 4 = 5200 - 320 = $4880 from the second buyer. The difference between Chris’s earnings would be 4880 - 4680 = $200. The answer is 200.

Q: Five months ago, Mike earned 10 times more money than Fred. If his salary has increased by 40 percent now, and Fred's salary then was $1000, calculate Mike's salary now.
A:
Five months ago, Mike earned ten times more money than Fred, and since Fred earned $1000, Mike earned 10 * 1000 = $10000 more than Fred. The total amount of money that Mike earned five months ago is $10000 + $1000 = $11000. Mikes salary has increased by 40 / 100 * $11000 = $4400. Mike's current salary is $11000 + $4400 = $15400. The answer is 15400.
