Riverton Sails currently produces boat sails and is considering expanding its operations to include awnings for homes and travel trailers. The company owns land beside its current manufacturing facility that could be used for the expansion. The company bought this land ten years ago at a cost of $84239 and spent $25665 on grading and excavation costs at that time. Today, the land is valued at $218287. The company currently has some unused equipment that it owns with a current market value of $44103. This equipment could be used for producing awnings if $10825 is spent for equipment modifications. Other equipment costing $315738 will be required. What is the amount of the initial (t0) cash flow for this expansion project?
