So to find the value of -3 do the following process:
Insert the -3 in the x’s in the equation on the top of the table
y= 5x -3x to the second power + 3
y= 5 (-3) -3(-3) to the second power + 3
Then continue to simplify the equation
y= -15 + 9 to the second power + 3
y= -15 + 84
y = 69
Y= 69 for the chart for -3
For b, c, and d insert the number in the x values and simplify like the previous equation.

<span>To get the break-even
point, you have to divide the fixed cost by the selling price of a mailbox less
the variable cost in making a mailbox. In this case, we will have to divide $192,827.00 by $39.99 less $25.43. So, the
break-even point will be 13244 units.</span>
