Tiffania Natural Snacks is contemplating an expansion. The finance manager is looking at buying a second machine that would cost $70,000 and last for 7 years, with no disposal value at the end of that time. Tiffania expects the increase in cash revenues from the expansion at $30,000 per year, with additional annual cash costs of $16,000. Tiffania's cost of capital is 8%, and the company pays no taxes because of its location in a special economic zone. Future Value of $1 table Future Value of Annuity of $1 table Present Value of $1 table Present Value of Annuity of $1 table Read the requirements Requirement 1.
