You can  put this solution on YOUR website! A manufacturer sells a product at $8.80 per unit, selling all produced. The fixed cost is $2,160 and the variable cost is $7.25 per unit. 
. 
Profit equation: 
P(x) = 8.80x - 7.25x - 2160 
P(x) = 1.55x - 2160 
where 
x is the number of units 
. 
(a) At what level of production will there be a profit of $4,100? 
Set P(x) = 4100 and solve for x: 
4100 = 1.55x - 2160 
6260 = 1.55x 
4038.71 units = x 
. 
(b) At what level of production will there be a loss of $1,200? 
Set P(x) = -1200 and solve for x: 
-1200 = 1.55x - 2160 
960 = 1.55x 
619.35 units = x 
. 
(c) At what level of production will the break-even point occur?  
Set P(x) = 0 and solve for x: 
0 = 1.55x - 2160 
2160 = 1.55x 
1393.55 units = x
