Question 1: If a firm produces 50 units of output and incurs a total cost of $3,000 and the variable cost is $550, calculate the firm's average fixed cost of production if it expands output to 55 units.

Question 2: If average total cost is $75 and average fixed cost is $25 when output is 40 units, what is the firm's total variable cost at that level of output?

Question 3: When the average total cost is $10 and the level of total cost is $9,000, what is the number of units the firm is producing?

Question 4: If 20 workers can produce a total of 250 units of a product and a 21^st worker has a marginal product of ten units, what is the average product of 21 workers?

Question 5: When a firm produces 50,000 units of output, its total cost equals $10.5 million. When it increases its production to 60,000 units of output, its total cost increases to $16.1 million. Within this range, calculate the marginal cost of output.

Question 6: Earl sells samosas. The cost of ingredients to make a samosa is $1.75. Earl pays his employees $40 per day. He also incurs a fixed cost of $80 per day.

a)Calculate Earl's variable cost per day when he produces 100 samosas using three workers?

b)Calculate Earl's average fixed cost per day when he produces 100 samosas using three workers?

c)What is Earl's total cost per day when he does not produce any samosas and does not hire any workers?
