Q: If 8 carpenters can make 50 chairs in 10 days, how many carpenters are needed to make 75 chairs in 10 days?
A: The carpenters need to produce 75 / 50 = 1.5 times as many chairs in the same number of days. It will require 1.5 times as many carpenters to produce the extra chairs, so 8 * 1.5 = 12 carpenters will be required. The answer is 12.

Q: Jim's bi-weekly gross pay is $1120. He automatically has 25% of his paycheck go into his retirement account. They also take $100.00 out of each paycheck for taxes. After money is taken out for retirement and taxes, how much money will be on Jim's paycheck?
A: He has 25% of his take - home pay automatically enrolled into his 401k so that's .25 * 1120 = $280.00. His take - home pay is $1120.00 and $280.00 is taken out for retirement so that leaves 1120 - 280 = $840.00. They also take $100.00 out of his paycheck for taxes so his paycheck will be issued for 840 - 100 = $740.00. The answer is 740.
Question: Darrel has 76 quarters, 85 dimes, 20 nickels and 150 pennies. If he drops all of his money into a coin-counting machine, they will convert his change into dollars for a 10% fee. How much will he receive after the 10% fee?
Answer: He has 76 quarters so that's 76 * .25 = $19.00. He has 85 dimes so that's 85 * .10 = $8.50. He has 20 nickels so that's 20 * .05 = $1.00. He has 150 pennies so that's 150 * .01 = $1.50. All total he has 19 + 8.5 + 1 + 1.5 = $30.00. They charge a 10% fee to count and convert his change into dollars so they will charge him .10 * 30 = $3.00. He had $30.00 and they charged him $3.00 in fees so he now has 30 - 3 = $27.00. The answer is 27.
