The interest rate of the financing is 2.7% am for a period of 24 months. Calculate the monthly value of the installments to be paid, assuming: a) GRV was paid at the end of the contract; b) payment of the GRV at the beginning of the contract in the form of an entry. Considering a total tax benefit of 34%(deduction), assemble the cash flow of this project.
