Functions with additional arguments

Let's add some arguments to the function definition!

Numeric data in scores represent students' performance scaled between 0 and 100. Your task is to rescale this data to an arbitrary range between low and high. Rescaling should be done in a linear fashion, i.e. for any data point \(x\) in a column:

\(x_{new}\) = \(x\frac{high -low}{100} + low\)

To do rescaling, you'll have to define the function rescale(). Remember, the operation written above can be applied to Series directly. After defining the function, you'll have to apply it to the specified columns of scores.
