Hello,

I've completed the calculations for parts b, c and d and I got different answers. I think there's something I'm missing. Is it possible to get details on the calculations?

For example see part b below and my calculations. May I please get some guidance?

18% + 0.40 x (1- 35%) x (18%-8%)

(0.18 + 0.40) x (0.65 x 0.62)

0.58 x 0.40 = 0.23
