145) Pooja has an annual salary of $98 351.00 and is paid biweekly. Her regular workweek is 32 hours.
a) What is Pooja's gross pay per pay period?
b) What is the hourly rate of pay?
c) What are the gross overtime earnings for Pooja if the overtime rate is one and three quarters the regular
hourly rate of pay and she works 8 extra hours?
Answer: a) Yearly salary = $98 351.00
Biweekly gross pay = 98 351/26 = $3782.73
b) Biweekly gross pay = $3782.73
Weekly gross pay = 3782.73/2 = $1891.37
Hourly rate = 1891.37/32 = $59.11
c) Hourly rate = $59.11
Gross overtime earnings = 59.11(1.75)(8) = $827.54

any additional net sales for the month, and is entitled to drawings of up to $1750 per month. During February,
Danny's gross sales amounted to $11 456 and sales returns and allowances of $512.
a) What is Danny's gross commission for the month?
b) If Danny drew $1235 in February, what is the amount due to him?
Answer: a) Gross sales = $11 456.00
Commission on first $5000 = 0.134(5000) = $670.00
Commission on next $3000 = 0.141(3000) = $423
Commission on additional sales = 0.15(11456 - 8000) = $518.40
Total gross commission  = $1611.40
b) 1611.40 - 1235 = $376.40

a) What is your average quiz grade in this course?
b) What is your average grade for the course overall?
Answer: a) Quiz Average = (80 + 90 + 80 + 90 + 80 + 50 + 80 + 70)/8 = 77.5%
b) Average course grade = [(77.5) 20 + (65)15 + (78)15 + (72)50] / (20 + 15 + 15 + 50)
= (1350 + 2145 + 3600)/100 = 70.95%
