"Definition of Fixed Costs: In production, fixed costs are the costs
that do not vary with the number of goods produced. In the short-run
factors like land and rent are fixed costs, whereas raw materials used
in production are not."
From "Fixed Costs - Glossary - Dictionary Definition of Fixed Costs":
"Variable costs are costs that vary directly with the number of
products produced. For instance, the cost of the materials needed and
the labour used to produce units isn't always the same."
From "Breakeven Analysis - Fixed Costs Variable Costs":
According to the above definitions we have that:
Fixed costs are:
Executive salaries $112,000
Variable costs are:
Factory labor $1.50 per unit
Raw material $0.70 per unit
Break-even = Fixed Costs / Contribution margin per unit
Contribution margin per unit = (Revenues - Variable Costs) / Units sold =
= Price per unit - Variable cost per unit
Break-even = Fixed Costs / (Price per unit - Variable cost per unit) =
= ($120,000 + $112,000) / [$6.00 - ($1.50 + $0.70)] =
= $232,000 / $3.80 =
= 61053 units
