Economic profit refers to the profit earned by deducting the implicit cost and the explicit cost from the total revenue.
Economic Profit = Total revenue - (Explicit cost + Impllicit Cost)
where Total Revenue = $100,000
Explicit Cost = $2000 + ($25000*10%) = $4500
Implicit Cost = $70000 + $10000 = $80000
Economic Profit = $100,000 - ($4,500 + $80,000)
Economic Profit = $100,000 - $84,500
Economic Profit = $15,500
Hence, Sid's Economic Profit is equal to $15,500
