The range of the function in the context of the problem is N(t) >= 18.75
The function is given as:
N(t) = 4.25t + 18.75
The value of t can only be 0 or more.
So, we have:
N(t) >= 4.25 * 0 + 18.75
Evaluate the product
N(t) >= 0 + 18.75
Evaluate the sum
N(t) >= 18.75
Hence, the range of the function in the context of the problem is N(t) >= 18.75
