Based on the data, a total of 13 students were wearing a green polo and jeans, and 12 students were wearing a yellow polo and jeans. Therefore, a total of 13 + 12 = 25 students out of the first 5 dozen students wore blue jeans and a polo shirt.%0D%0A%0D%0ATo find out how many out of the 900 BMS students could be expected to be wearing blue jeans and a polo shirt, we can use the proportion method:%0D%0A%0D%0A5/12 (portion of students wearing blue jeans and a polo shirt) = x/900%0D%0A%0D%0AMultiplying both sides by 900, we get:%0D%0A%0D%0Ax = 5/12 * 900%0D%0A%0D%0Ax = 375%0D%0A%0D%0ATherefore, out of the 900 BMS students, approximately 375 students could be expected to be wearing blue jeans and a polo shirt.
