26 Rows 5 to 7, 21 and 23, plus cell B8 are data.
28 The formula in cell C9 is: =C6*C8. Then copy formula in cell C9 to cells D9, E9, and F9.
29 The formula in cell C10 is: =C9*(1-.4). Then copy formula in cell C10 to cells D10, E10, and F10.
30 The formula in cell B11 is: =B7*B8. Then copy formula in cell B11 to cells C11, D11, E11, and F11.
32 The formula in cell C14 is: =C10+C12. Then copy formula in cell C14 to cells D14, E14, and F14.
33 The formula in cell E16 is: =F14/(B21-F5).
34 The formula in cell B22 is: =NPV(B21,C14:E14)+E16/(1+B21)^3.
