lakia 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 $1,800. toy sales are expected to produce net cash inflows of $2,300, $2,900, $3,500, and $4,600 over the next four years, respectively. should lakia add toys to her store if she assigns a 3 year payback period to this project? why or why not?
