A business firm borrows $1,000 for an investment project that will increase its net revenue by $1,100 two years from now, at which point it will pay back the loan and accumulated interest. Will the $1,100 be sufficient to cover the full amount of the loan repayment?

Yes, because $1,100 > $1,000.

Only if the interest rate on the loan is 1% or less.

Yes if the interest rate on the loan is 4%, but no if it is 6%.

Yes at any interest rate less than 10%.
