Answer:
Her accumulated earnings for the month total $2208
Step-by-step explanation:
A dental lab technician receives $14 hourly for day shifts and $18 hourly for night shifts.
During one month:
She completed six 4-hour day shifts
Thus, total hours worked = 
Three 8-hour day shifts = 
Three 10-hour day shifts = 
Total day hours = 24+24+30=78 hours
Hourly rate for daytime work = $14
Cost for 78 day hours = 
Five 6-hour night shifts= 
Four 8-hour night shifts =
Total night hours = 30+32=62 hours
Hourly rate for nighttime work = $18
Cost of 62 night hours = 
Thus, total monthly earnings = $1092+$1116 = $2208
Consequently, her total pay for the month amounts to $2208
