hi,
In the question 10. B) part II calculate the minimum target contribution...
I'm struggling to understand in the equation below:
(4 x X x 0.893) + (9 x X x 0.797) + (5 x X x 0.712)= 0.426932
where X= change the contribution to sales ratio (%)
where the numbers 4, 9 and 5 are coming from??
Can anyone explain?
thanks.
