40*7 + 9*7*1.5 + 12*7*2
To calculate Jan Quint's earnings, we need to consider her regular hours, overtime hours, and holiday hours separately and apply the appropriate rates for each category.
1. Regular Hours:
Jan worked 40 regular hours, and her rate is $7.00 an hour. So her earnings for regular hours can be calculated as follows:
Regular earnings = Regular hours * Hourly rate
= 40 hours * $7.00/hour
= $280.00
2. Overtime Hours:
Jan worked 9 hours of overtime, and she is entitled to time-and-a-half for overtime. This means her overtime rate is 1.5 times her regular rate ($7.00/hour).
Overtime earnings = Overtime hours * Hourly rate * Overtime multiplier
= 9 hours * $7.00/hour * 1.5
= $94.50
3. Holiday Hours:
Jan worked 12 hours on holidays, and she is entitled to double her regular rate on holidays. This means her holiday rate is twice her regular rate ($7.00/hour).
Holiday earnings = Holiday hours * Hourly rate * Holiday multiplier
= 12 hours * $7.00/hour * 2
= $168.00
Total earnings = Regular earnings + Overtime earnings + Holiday earnings
= $280.00 + $94.50 + $168.00
= $542.50
Therefore, Jan Quint earned $542.50 last week.
