please explain this properly step by step manually

A company must decide whether to build a small, medium, or large grocery store. Marketing research findings indicate a 0.35 probability that demand will be low and a 0.65 probability that demand will be high. If the company builds a small grocery store and demand is low, the net present value will be $150,000. If demand is high the company can buy its additional grocery needs from a wholesaler and realize a net present value of $100,000 or expand and realize a net present value of $120,000. If the company builds a medium grocery store and demand is low, the net present value will be $175,000; if demand turns to be high the company could do nothing and realize a net present value of $100,000, or expand and realize a net present value of $135,000. If the firm builds a large grocery store and demand is low, the net present value will be $50,000; if demand turns out to be high the net present value will be $250,000. a. Develop a decision tree for this problem. b. Analyze the decision tree and determine which alternative should be chosen
