    Help setting up problem.

    A "square" of shingles covers 100 square feet. For a roof of x square feet, the function N(x)= x/100 models the number N of squares that will be needed. Evaluate N to determine the number of squares required for a roof of 5100 square feet. How should I arrange the information to arrive at an answer?

    Hello,

    with the given values you know that x = 5100. Plug in this value into the equation and you'll get:

    N(5100)=\frac{5100}{100}= 51 \text{ squares}
