Maxwell Electric has secured a deal to purchase a plant 10 years from now for $2,500,000. Their plan is to pay 20% of the value of the property and finance the rest. The accountant of the company told the management that they need to invest $250,000 in a fund that returns 7% per year interest now so that in ten years, they will have enough money to pay the 20% down payment. Is the accountant correct?
