The total cost for Pete Corporation to produce x bags of peanuts is:
C = 21,437 + 2.05x
Here, 21,437 is the fixed cost, and 2.05x is the variable cost.
The revenue for selling x bags of peanuts is:
R = 3.99x
Because each bag sells for $3.99.
The break-even point is reached when the cost and the revenue are equal. Once past the break-even point, Pete will start getting positive profit, before the break-even point, there are losses.
The equilibrium point leads us to the equation:
21,437 + 2.05x = 3.99x
Subtracting 2.05x:
3.99x - 2.05x = 21,437
Simplifying:
1.94x = 21,437
Dividing by 1.94:
x = 21,437 / 1.94
x = 11,050
Pete Corporation must produce and sell 11,050 bags of peanuts to start getting profit.
