Hi I can not figure out how to get PV factor for this problem

Peng Company is considering an investment expected to generate an average net income after taxes of $3,300 for three years. The investment costs $45,900 and has an estimated $9,900 salvage value.

Assume Peng requires a 5% return on its investments. Compute the net present value of this investment. Assume the company uses straight-line depreciation. (PV of $1, FV of $1, PVA of $1, and FVA of $1) (Use appropriate factor(s) from the tables provided. Negative amounts should be indicated by a minus sign.)

Cash Flow Amount x PV Factor Present Value Annual cash flow Assessment Tool iFrame Present Value of an Annuity of 1 $15,300 x = 0 Residual value Present Value of 1 = 0 Net present value
