Alicia is considering adding toys to her gift shop. She estimates that the cost of inventory will be $7,500. The remodeling expenses and shelving costs are estimated at $1,500. Toy sales are expected to produce net cash inflows of $1,800, $2,700, $3,200, and $3,400 over the next four years, respectively. Should Alicia add toys to her store if she assigns a three-year payback period to this project? Why or why not?
