A real estate agent earns a 6% commission on each property she sells. If she sells a detached house for $200,000 and a cottage for $180,000, how much commission will she earn? A. $10,800
B. $20, 000
C. $22,800
D. $12,000

B. 22,800
The letter (b) might vary depending on how it was set up so it might be (c), (d), or even (a). Just make sure 22,800 comes after the letter :)
