To determine the equation to represent this situation, we can use 2.5x to show the amount of profit per product, and a y intercept value of -550 to show the cost for rent. Now, we have the equation y=2.5x-550.
The break even point is when the profits balance out the expenses, so in this case, y should equal 0.
0=2.5x-550
Add 550 to both sides...
550=2.5x
Divide both sides by 2.5...
x=220
So, our answer is 220 products.
For the first one it would be C.
