With total fixed cost of $400, a firm incurs an average total cost of $3 and average variable cost of $2.50. the amount of output produced by the firm must be rev: a. 200 units. b. 400 units. c. 800 units. d. 1,600 units.

c. 800 units.

Explanation:

The total cost can be calculated as follows;

Total Cost = Fixed Cost + Variable Cost ----------------Equation 1

If x is the number of units produced then;

Total Cost = $3.00 x

Variable Cost = $2.50 x

Fixed Cost = $400

By applying the above given costs in the equation 1 to find the number of units produced;

$3.00 x = $400 + $2.50 x

Subtract the above Equation by $2.50 x, we get;

$3.00 x - $2.50 x = $400

$0.50 x = $400

Dividing the above equation by $0.50, we get;

x =

x = 800 units.

Hence, option 'c' will be correct answer.
