Based on the cashflows of these projects and the IRR, the project with the higher IRR would be CFS and the value that would be foregone is $12.72.
Using a spreadsheet, you can find the IRR of both projects to be:
CFS = 17.13%
CFL = 13.95%
CFS NPV is:
= 675 / 1.0775 + 650 / 1.0775² - 1,050
= $136.31
CFL NPV is:
= 360 / 1.0775 + 360 / 1.0775² + 360 / 1.0775³ + 360 / 1.0775⁴ - 1,050
= $149.03
The value foregone by picking CFS instead of CFL is:
= 149.03 - 136.31
= $12.72
