Silverberg Manufacturing is considering investing $$90,000$ in a new piece of machinery that will generate net annual cash flows of $$40,000$ each year for the next $4$ years. The machine has a salvage value of $$15,000$ at the end of its $4$ year useful life. Silverberg's cost of capital and discount rate is $6\%.$ What is the dollar amount that we would multiply the factor by when using the PV of an Annuity table?

$$160,000$

$$15,000$

$$90,000$

$$40,000$
