Pinder Ltd is considering building a toy factory for $372,831. It is a five-year project, after which the disposal costs will cancel out the salvage value from the factory. During each of the five years, Pinder Ltd estimates sales volume to be 33,751 units, selling price to be $27, variable cost to be $6, and fixed costs to be $110,226.
