Can someone help me answer this?? I am confused...

Three FM radio stations (A, B, and C) are competing for customers in the same market area. Through an aggressive advertising campaign, each month station A is capturing 11% of station B's customers and 5% of station C's customers. (Hint: The phrase "station A is capturing 11% of smtion B's customers" means that 11% of the listeners are moving from B to A, not the other way around.) At the same time, station A is losing only 2% of its customers to B and 2% of its customers to C. Additionally, each month 1% of B's customers switch to C, and 1% of C's customers switch to B. Initially, A and 5 each have 30% of the listeners and C has 40%. Use this information to answer the following questions. (Give your answers correct to three decimal places. Note that you are asked to give decimal values and not percentages. For example, you would need to enter 0.528 as opposed to 52.800%.) (a) What fraction of the listeners will A have after 3 months? (b) What fraction of the listeners will 3 have after 3 months? (c) What fraction of the listeners will c have aer 3 months
