Answer

### The independent variable, \( x \), represents the number of hours since snow began falling, and the dependent variable is the total amount of snow, because the total amount of snow depends on the number of hours. A function relating these variables is \( K(x) = 3x + 4 \). So \( K(4) = 16 \) inches, meaning after 4 hours.

Explain

## Step 1: Identify the Independent and Dependent Variables<br />### In this context, the independent variable \( x \) is the number of hours since snow began falling. The dependent variable is the total amount of snow on Mamadou's lawn, as the amount of snow depends on the number of hours it has been snowing.<br />## Step 2: Formulate the Function<br />### Since it initially snowed 4 inches and then at a rate of 3 inches per hour, the total amount of snow \( K(x) \) after \( x \) hours can be given by the function \( K(x) = 3x + 4 \).<br />## Step 3: Calculate \( K(4) \)<br />### Substituting \( x = 4 \) into the function: \( K(4) = 3(4) + 4 = 12 + 4 = 16 \).
