thoughts?

there are two parts of the fee (the fixed rental, vs. the daily late fee)
as well as two parts of the equation (the 2, and the 0.25x part)

do you think the constant (2) represents the fixed rental, or the daily late fee? as a major hint, notice how 2 is *not* multiplied to x, the number of days
