14. Jack is considering adding toys to his general store. He estimates that the cost of inventory will be $4,200. The remodeling expenses and shelving costs are estimated at $1,500. Toy sales are expected to produce net cash inflows of $1,200, $1,500, $1,600, and $1,750 over the next four years, respectively. Should Jack add toys to his store if he assigns a three-year payback period to this project?
