In part a) of this question, what should I write in the place of average price for hair services per male client for 20X8. I calculated the average price per female client for hair services in 20X9 to be 23.32518.
They did not have any male clients in 20X8 (see the first two paragraphs of the question, and the list of non-financial measures given in the question).
I do not know how you calculated 23.32518. The question says that the prices for female clients was not increased and so was the same as in 20X8, which is 200,000/8,000 = $25.
