A firm is must choose to buy the GSU-3300 or the UGA-3000. Both machines make the firms production process more efficient which in turn increases incremental cash flows. The GSU-3300 produces incremental cash flows of $24,044.00 per year for 8 years and costs $104,482.00. The UGA-3000 produces incremental cash flows of $28,253.00 per year for 9 years and cost $125,873.00. The firms WACC is 9.50%. What is the equivalent annual annuity of the GSU-3300? Assume that there are no taxes.

(I understand how to compute the first step to find NPV, but calculating equivalent annuity is where I am stuck. Can you please write out each step for that?)
