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?
Thoughts? Step-by-step reasoning:
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.
Thus, the answer is 27.
