Aaron is a salesman that earns a base salary of $1,200.00 per month and a commission of 5% on the amount of sales he makes. One month Aaron received a paycheck for $1,811.00. Find the amount of his sales for the month.

1811 - 1200 = 611 commission

.05 * sales = 611
sales = $12,220

To find the amount of Aaron's sales for the month, we need to first determine the commission he earned. The base salary is fixed at $1,200.00, so in order to find the commission amount, we subtract the base salary from the total paycheck.

Total paycheck - Base salary = Commission

$1,811.00 - $1,200.00 = $611.00

Now, we can calculate the sales amount by dividing the commission earned by the commission rate (5%).

Commission / Commission rate = Sales amount

$611.00 / 0.05 = $12,220.00

Therefore, Aaron's sales for the month were $12,220.00.
