Answer :

To find the commission amount from a sale of [tex]$143,400 at a commission rate of 5.5%, follow these steps:

1. Convert the Percentage to a Decimal:
- The commission rate is given as 5.5%. To use it in a calculation, convert it to a decimal by dividing by 100.
- \( 5.5\% = \frac{5.5}{100} = 0.055 \).

2. Calculate the Commission Amount:
- Multiply the sale price by the commission rate in decimal form.
- \( 143,400 \times 0.055 = 7,887.0 \).

Therefore, the commission amount is $[/tex]7,887.00.
