The cost of shipping can be modeled with a linear function of the form \( f(x) = mx + b \), where:

- \( f(x) \) is the total cost of shipping,
- \( m \) is the variable cost per pound,
- \( x \) is the weight of the box in pounds,
- \( b \) is the fixed flat packing fee.

In your case:

- The flat packing fee, \( b \), is $3.
- The cost per pound, \( m \), is $1.50.

Thus, the function for the shipping cost would be:

\[
f(x) = 1.5x + 3
\]

Where:
- \( f(x) \) represents the total shipping cost,
- \( x \) is the weight of the box in pounds.

This linear equation can be used to calculate the total shipping cost for any given weight \( x \).
