A salesman has a monthly fixed income of 1700.00 $, plus $25.00 for each electronic unit he sells.

Question: Find the total monthly income for the sale of x units.

Let x equal the total monthly income for the sale of x units

Fixed cost is 1700

variable cost would be 25x

I'm mississing some sort of logic here and i just cant figure it out... I see it as T(x) = 25x + 1700.

Any help would be greatly appreaciated! thanks. (Hi)
