Each year Mark works 40 hours per week for 50 weeks. Last year Mark was paid a total of $20000. If this year his hourly pay rate is raised by $0.50, what is the total amount that Mark will be paid this year?

A. $30000
B. $25000
C. $22500
D. $21500
E. $20020

Total hours worked for 50 weeks = 50*40 = 2000 hours.
Hourly rate = 20000/2000 = $10/hr
New hourly rate = $10.50

Therefore, total amount that Mark will be paid this yr = 10.50 * 2000 = $21000.
