Answer:
534. 75
Step-by-step explanation:
let the income of kellys sister be x
kellys income=x+15% of x

or, x=465
kellys income=23×465/20
=534. 75
Probability=number of specific outcomes / total possible outcomes
P(g)=12/(12+8)
P(g)=12/20
P(g)=3/5

This is not really a business or accounting forum, its a maths forum, so you need to be clearer about business or accounting terms such as total cost, selling price, selling cost.
