This is a great one for plugging in. Pick a number for x, such as $200,000. If x = $200,000, then the 10% commission will be on $100,000. 10% of $100,000 is $10,000. So the total earnings is $25,000 + $10,000 or $35,000. Then plug $200,000 in for x in each of the answer choices and see which one yields $35,000.You should get:
A. $45,000
B. $55,000
C. $145,000
D. $15,000
E. $35,000
So the answer is E.
Take care.
