M&B Tooling Ltd. is assessing two available options for the purchase of new equipment with a negotiated cash price of $100,000. The manufacturer is willing to accept a down payment of 20% of the purchase price and an instalment note for the balance. The note would require quarterly fixed principal payments (plus interest) starting October 1, 2023, for a period of two years. M&B has a proposal from its bank for an instalment loan for two years that requires a fixed blended monthly payment (including both principal and interest) starting August 1, 2023. The loan would be for 80% of the equipments purchase price. The current market rate of interest is 8%. Both contracts have an interest rate of 8%. Instructions

Calculate the amount of the payments required of M&B under each alternative. Use formulas not excel or financial calculator.

Is there any measurement uncertainty in determining which option is best for M&B? Which discounted cash flow approach should be used in the comparison of the two alternatives?

Please show the workings and formula.
