4.   Jan Quint earns $7.00 an hour at her job and is entitled to time-and-a-half for overtime, and double time on holidays. Last week she worked 40 hours of regular time, 9 hours of overtime, and 12 hours of holiday time. How much did she earn last week? 

    A. $542.50 B. $348.75 C. $532.00 D. $524.50

A?

Overtime = 7 * 1.5 = 10.50 per hour

Holiday time = 14 per hour

(40 * 7) + (9 * 10.5) + (12 * 14) = 542.50

A is right.

To calculate Jan Quint's earnings last week, we need to calculate her regular time, overtime, and holiday time separately and then add them together to get the total.

1. Regular Time Earnings:
Jan worked 40 hours of regular time, and she earns $7.00 per hour. So, her regular time earnings would be 40 hours * $7.00 = $280.00.

2. Overtime Earnings:
Jan worked 9 hours of overtime, which is 1.5 times her regular hourly rate. So, her overtime earnings would be 9 hours * $7.00 * 1.5 = $94.50.

3. Holiday Time Earnings:
Jan worked 12 hours of holiday time, which is 2 times her regular hourly rate. So, her holiday time earnings would be 12 hours * $7.00 * 2 = $168.00.

Now, let's add up all the earnings:
Regular time earnings + Overtime earnings + Holiday time earnings = $280.00 + $94.50 + $168.00 = $542.50.

Therefore, the correct answer is A. $542.50.

To calculate Jan Quint's earnings for last week, we need to calculate her earnings for regular time, overtime, and holiday time separately, and then add them together.

1. Regular time: Jan worked 40 hours of regular time at $7.00 per hour, so she earned 40 * $7.00 = $280.00 for regular time.

2. Overtime: Jan worked 9 hours of overtime. Since she is entitled to time-and-a-half for overtime, she will earn 1.5 times her hourly wage for each overtime hour. Therefore, for overtime, Jan earned 9 * ($7.00 * 1.5) = $94.50.

3. Holiday time: Jan worked 12 hours of holiday time. Since she is entitled to double time on holidays, she will earn 2 times her hourly wage for each holiday hour. Therefore, for holiday time, Jan earned 12 * ($7.00 * 2) = $168.00.

Now, we can calculate Jan Quint's total earnings for last week by adding her earnings for regular time, overtime, and holiday time:

Total earnings = earnings for regular time + earnings for overtime + earnings for holiday time
Total earnings = $280.00 + $94.50 + $168.00 = $542.50

So, the correct answer is A. $542.50
