At a certain university, three bookstores—the university bookstore, the campus bookstore, and the book mart—currently serve the university community. from a survey conducted at the beginning of the fall quarter, it was found that the university bookstore and the campus bookstore each had 25% of the market, whereas the book mart had 50% of the market. each quarter, the university bookstore retains 80% of its customers but loses 10% to the campus bookstore and 10% to the book mart. the campus bookstore retains 75% of its customers but loses 10% to the university bookstore and 15% to the book mart. the book mart retains 90% of its customers but loses 5% to the university bookstore and 5% to the campus bookstore. if these trends continue, what percentage of the market will each store have at the beginning of the second quarter? the third quarter? (round your answers to two decimal places.)
