Pablo is making ramps of different lengths. The ramps are made with rectangular and square wooden boards. The relationship between the length of the ramp in feet, f(n), and the number of square boards used, n, is represented by the function below.
f(n) = 20n + 3 , where 2 ≤ n ≤ 6
Which statement is correct about the range of the length of the ramp for the given domain?
