The problem says that the band raised $2000 and wants to divide it equally among the members of the band, then, we must divide the raised value by the number of members (not given), which we will represent as "m". That division will be
As we can see it's a correct expression, let's do a simple test, let's suppose it's a 4-members band, then m = 4. If we want to divide 2000 equally to 4, each member will receive 500, using our expression
As we expected.
Therefore, the correct answer is the letter B.
