Suppose you own a sandwich shop with fixed costs of $1,000/month and marginal costs of $2.00/sandwich. If the price is $6/sandwich, 500 sandwiches are sold. If the price is $4.50/sandwich, 800 sandwiches are sold.

A)  Use these figures to calculate the price elasticity.

B) Calculate the profits and profit margins (profit/total cost) associated with the price at $6/sandwich and at $4.50/sandwich. Given these calculations, what price should you charge for sandwiches?

Solutions

Expert Solution

A)  Use these figures to calculate the price elasticity.

As price and demand are inversely related, the elasticity will always be negative so it is reported in absolute terms only without the minus sign so it is 1.62

B) Fixed cost is $1000 or the cost that is incurred when output = 0

Now we have to calculate the Profit margin

As profit is the same in either situation, it is better to sell more and generate higher total revenue. This is because the fixed cost remains constant so total cost goes on decreasing, leading to a higher profit margin at higher output.

Marginal costing is a technique that distinguishes between variable costs and fixed costs. In this approach to costing, only the variable costs of production are charged to cost units. Marginal costing and the concept of contribution are fundamental to the breakeven analysis or ‘cost-volume-profit’ (CVP) technique. Required: (a) Explain the concept of contribution and its importance to the CVP technique. (b) Describe the nature of each of the ‘dropping a product or service’ and ‘special contract’ decisions for which the...

If referencing a perfectly competitive firm: Marginal Revenue (MR) = marginal costs (MC) at 1,000 units of production. The price per unit of the product is $22 at this output. The TOTAL FIXED COSTS (TFC) at this output=$10,000. AVERAGE TOTAL COSTS (ATC) = $25 per unit at this output. 1) Should the firm continue to produce at this output? Why or why not? 2) What is the total profit or loss at this level of production? Show calculation.
