Answer:
$110
Step-by-step explanation:
We are looking for the decrease in money per desk purchased. Because the x-axis is the number of desks purchased, what we have to find is the (opposite) of the slope. The formula to represent slope can be written as:

We can substitute the points given, (2, 480) and (5, 150) and simplify:

We would multiply by -1 because we are asking for the decrease, and negative increase is decrease. -1 * -110, gives us $110
The answer would be 680 because 20% of 850 is 170 so 850-170=680.
