To find the commission rate, we need to divide the commission by the sale amount. This will give us the rate as a decimal, which can be converted to a percentage by multiplying by 100.
Step 1: Identify the Given Values
We are given the sale amount and the commission. Specifically, the sale amount is \(\$14,400\) and the commission is \(\$432\).
Step 2: Calculate the Commission Rate
To find the commission rate, we use the formula:
\[
\text{Commission Rate} = \left(\frac{\text{Commission}}{\text{Sale}}\right) \times 100
\]
Substituting the given values:
\[
\text{Commission Rate} = \left(\frac{432}{14400}\right) \times 100 = 3.0
\]
