10. Implanting a stent is a roughly Php 850,000 operation, of which the standard stent is only a Php 65,000 component. - Operation cost = Php 785,000 - - Standard Stent Cost = Php 65,000 -Assume the procedure must be repeated 25% of the time due to restenosis -Solve for total expected cost 11. Consider the scenario in number 10. Solve for the exchange value of the Drug Eluting Stent if it reduces restenosis to 10%. 12. How much will be the differential value?
