To calculate Mr. Kirkland's commission on a home that sells for $250,000 at a 7 percent commission rate, you can use the following formula:
\[ \text{Commission} = \text{Sale Price} \times \text{Commission Rate} \]
Substituting the given values:
\[ \text{Commission} = 250,000 \times 0.07 \] \[ \text{Commission} = 17,500 \]
Mr. Kirkland would earn $17,500 on a home that sells for $250,000.
