Jan quint earns 11.00 an hour at her job and is entitled to time and a half for overtime, and double tie 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. 720.50 b. 852.50 c.803.00 d.612.00

Let's find an expression for Jan's earnings in terms of normal wage, hourly wage, and overtime wage:
x= normal hours
y= OT hours
z = holiday hours
Jan earns 11/hour on normal time.
She earns 11 * 1.5 = 16.5/hour on OT
She earns 11 * 2 = 22/hour on holidays
The expression for her earnings is:
11x + 16.5y + 22z = earnings
Plugging in her hours (40 reg, 9 OT, 12 holiday):
11(40) + 16.5(9) + 22(12) = earnings
440 + 148.5 + 264 = earnings

earnings = 852.50
