There is no picture, but you would substitute the first number for the x and the second for the y
First of all, we need to deduce the price of a single camera:

Now, we know that he profits 36 dollars from each camera. So, we are asking: which percentage of 150 is 36? We have

This equation literally says: 36 is x-percent of 150. And we need to solve for x:

The cross section is a rectangle, because the shadowed area shows a right angle on all four sides.
