Answer:
Fixed costs cannot be changed in the short run and are the same regardless of the volume of production. Variable costs vary with production but can b changed in the short run.
Fixed costs:
- Interest on company issued bonds
- Real estate taxes
- Executive salaries
- Insurance premiums
- Rental payments on leased office machinery.
Variable costs:
- Advertising expenditures
- Fuel
- Shipping charges
- Payments for raw materials
- Wage payments
- Sales taxes
All costs are variable in the long run because all costs can be changed by investment and planning. For instance, over the long term, the company could buy the leased office machinery and not have to pay rent on it thereby stopping that fixed cost.
