[Question]A car uses 20 gallons of gas to travel 400 miles. Mr. Montero's car has 8 gallons in it. How many more gallons of gas does he need to travel 600 miles, back and forth?
[Answer]Mr. Montero is traveling a total distance of 600 miles + 600 miles = 1200 miles. There are 1200 miles / 400 miles = 3 sets of 400 miles in 1200 miles. So Mr. Montero needs 20 gallons / set x 3 sets = 60 gallons in all. Since his car has 8 gallons already, then he needs to add 60 gallons - 8 gallons = 52 gallons more. The answer is 52.

[Question]Irene earns $500 if she works for 40 hours a week and gets an extra $20 for every hour of overtime. If she worked 50 hours last week, calculate her total income.
[Answer]If Irene worked 50 hours last week, the total number of hours counting as overtime is 50 - 40 = 10 hours. Since she's given $20 for every hour of overtime, she earned 10 * $20 = $200 in overtime. Her total income, including the overtime, is $500 + $200 = $700. The answer is 700.
