The Customer Services department needs to invest in upgraded headsets for the 200 call centre agents. Prudence, the Contact Centre Manager, has done her research and plans to buy superior quality noise-cancelling headsets for the 200 call-centre agents at the bulk price of R1788.88 per unit. Each headset has a three (3) year warranty. After the three (3) years, the residual value of each headset is R0.00 as working headsets will be donated, and the broken headsets scrapped. Prudences projected income statement identified the annual net cash flows due to retained customers and new customer spending after tax is estimated at R720.00 per customer service agent headset unit in year one, R763.20 in year two, and R809.00 in year three.
