Answer 1

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 $b$:

$$b=\frac{250}{5}=50$$

So, the number of students who can choose band is $\boxed{{\displaystyle 50}}$.
