To solve this problem, let's use a proportional relationship.

Let b represent the number of students who choose band, and c represent the number of students who choose choir. According to the problem, we have:

  1. The total number of students is 250:
    b+c=250

  2. There are four times as many seats in choir as there are in band:
    c=4b

Now we can substitute the second equation into the first equation:

b+4b=250

This simplifies to:

5b=250

Now, we can solve for b:

b=2505=50

So, the number of students who can choose band is 50.
