I'm wondering if I got this question right. A car salesman receives a commission of 10% of the selling price of a car. Find the commission the salesperson earns for selling a car for $12,300. The answer I got was $12,3000.

Obviously, you are wrong.

0.1 * 12,300 = ?

0.1 x 12,300 = 1230. Thank you, I had a brain fart there.

You're welcome. :-)

To find the commission the salesperson earns for selling a car for $12,300, you need to calculate 10% of the selling price.

To do this, you need to multiply the selling price by 10% (0.10).

Mathematically, the commission can be found using the formula:

Commission = Selling Price * Commission Rate

In this case, the selling price is $12,300 and the commission rate is 10% (0.10).

So, to find the commission, you can multiply the selling price by the commission rate:

Commission = $12,300 * 0.10

Calculating this expression:

Commission = $1,230

Therefore, the commission the salesperson earns for selling a car for $12,300 is $1,230, not $12,3000.
