Answer:
In unitary terms, the average cost varies because the fixed costs are divided by higher or fewer units.
Explanation:
The average cost per unit varies according to production levels. First, <u>we need to clarify that fixed costs remain constant in the relevant range. </u>Between levels of production, the total fixed cost don't change.
In unitary terms, the average cost varies because the fixed costs are divided by higher or fewer units. Therefore, a fixed cost of $100 in 100 units is $1 per unit; but, in 50 units is $2 per unit. In unitary terms, variable cost remains the same.
<u>Finally, in total terms, fixed costs (in the relevant range) remains constant and total variable cost varies with production. </u>In unitary terms, variable cost remains constant and fixed cost varies.
