Bills accounting profit is equals to revenue ($250,000) minus explicit (monetary) cost (50,000 and 30,000), while his economic profit is equals to accounting profit minus implicit (opportunity) cost (3,000 and 100,000). Accounting profit is $170,000 and Economic profit is $67,000.

Economic profit is always lower than accounting profit because explicit costs and implicit costs are both deducted to revenue. Implicit costs are cost that he should have earned if he gives up his present resources. These costs are projected cost and are not yet incurred.

explanation:

a lump sum means that the father of the example made one deposit and leave it be.

we need to know the value of a capital that generated at 4.05% per year during 28 years the sum of $48,613.24

now clearing the formula to solve for capital we got:

and we reach the answer investment = $14,174.20
