The answer to this question:
1596/17 or 93.88 or 93 15/17
The equation that best represents the total earnings for the salesman is letter c which is e=40,000+200 xc
It is because, in order to get the full earnings, you have to add the base salary to the commission that the salesman receives. Whereas, the $40,000 is attached to the commission where the $200 is multiplied to c (every car the salesman sells
So one third means you mutilply by 3 so 3x5 is 15 model cars
I think you would distribute what is in the parentheses and then make it so only a and b are on the left and i and the other characters that can be simplified are on the left but feel free to Google it.
