(3pt each) Solve for the unknown in each cash flow diagram. Assume i=5% and use the engineering economics tables to solve these problems. Note: Year 1 is not pictured on the cash flow in part B because nothing occurs then. The annual series does not begin until year 1 and pays at the end of that year (year 2). A) A=$500 50 (yrs) P=?
