Mr. Corbin is a salesman. He gets a 5% commission on all sales between $100 and $500 and a 10% commission on all sales above $500. His commission on sales of $783 was:

you could have appended the correction to the original post. Anyway,

783-500 = 283
Apparently he makes no commission on the first $100. Assuming that, he makes

0% on 100 = 0.00
5% on 400 = 20.00
10% on 283 = 28.30
Total = 48.30

If I made a mistake on the first $100, make the fix and adjust the total.

To calculate Mr. Corbin's commission on sales of $783, we need to determine the amounts of sales that fall within each commission rate bracket.

First, let's calculate the amount of sales that fall between $100 and $500.
Sales between $100 and $500 = $500 - $100 = $400.

Next, let's calculate the amount of sales that exceed $500.
Sales above $500 = $783 - $500 = $283.

Now, we can determine the commission for each bracket.

Commission for sales between $100 and $500:
5% commission rate = 5/100 = 0.05.
Commission = $400 * 0.05 = $20.

Commission for sales above $500:
10% commission rate = 10/100 = 0.10.
Commission = $283 * 0.10 = $28.3.

Finally, we can calculate the total commission by adding the commission from each bracket.

Total commission = Commission for sales between $100 and $500 + Commission for sales above $500.
Total commission = $20 + $28.3 = $48.3.

Therefore, Mr. Corbin's commission on sales of $783 was $48.3.

To find Mr. Corbin's commission on sales of $783, we need to determine the two parts of his commission: the first part for sales between $100 and $500, and the second part for sales above $500.

First, let's find the commission for sales between $100 and $500.

Step 1: Calculate the sales amount between $100 and $500:
$500 - $100 = $400

Step 2: Multiply the sales amount by the commission rate for this range:
$400 * 5% = $20

So, for sales between $100 and $500, Mr. Corbin's commission is $20.

Next, let's find the commission for sales above $500.

Step 3: Calculate the sales amount above $500:
$783 - $500 = $283

Step 4: Multiply the sales amount by the commission rate for sales above $500:
$283 * 10% = $28.30

So, for sales above $500, Mr. Corbin's commission is $28.30.

Finally, let's add both commissions together to find the total commission:
$20 + $28.30 = $48.30

Therefore, Mr. Corbin's commission on sales of $783 is $48.30.
