Las Cruces' Virgin Galactic is considering two materials for certain parts in a reusable space vehicle: carbon fiber reinforced plastic (CFRP) and fiber reinforced ceramic (FRC). The costs are shown below. Which should be selected on the basis of a present worth comparison if MARR = 10% per year? (a) Solve using tabulated factors. (b) (Spreadsheet exercises) Solve using single-cell functions. (c) Using your spreadsheet functions, will the selection change if the estimated life of the CFRP material is 4, rather than 2, years?
