You can put this solution on YOUR website! B is the answer. D would work for the first part in that it could be $800 per car in the first week, but then the $400 per car the second week violates what was said.
-
C can't work because while it could be right for $800, 400x is not a total commission of $1200; 400x is not known unless x is known.
-
A is not right because she didn't make x dollars the second week but $400x dollars.

In my view, the post is worded, formulated and presented INCORRECTLY.
It is incorrect in its first statement,
because it DOES NOT explain what the variable "x" is.
From the first glance, it is CLEARLY SEEN that the author of this post is INCOMPETENT and UNPROFESSIONAL
in formulations of Math problems.
