Nope. Your answer has him earning just over $2.00 an hour.
To calculate how much Mr. White has earned, we need to multiply the number of hours worked by his hourly rate. Here's how you can do it step by step:
1. Convert the mixed number into an improper fraction:
40 1/2 = (40 * 2 + 1) / 2 = 81/2
2. Multiply the number of hours worked by the hourly rate:
Earnings = (81/2) * $23.60
To simplify multiplying a fraction by a decimal, you can multiply the numerator with the decimal and then divide the result by the denominator.
3. Calculate the earnings:
Earnings = (81/2) * $23.60 = (81 * $23.60) / 2
Multiply the numerator of the fraction by the decimal:
Earnings = ($1,912.40) / 2
Divide the result by the denominator:
Earnings = $956.20
Therefore, Mr. White has earned $956.20 for working 40 1/2 hours in repairing the house.
