Answer: The total is $13,133.33
Explanation:
We know that Edward's paycheck was $788
He has a base salary of $200, so the commission is:
$788 - $200 = $588
Now, we know that if he sells $10,000, his commission is a 4%.
So let's suppose that he sold exactly $10,000
Then his commission is the 4% of $10,000, this is:
Commission = (4%/100%)*$10,000 = $400
This is not enough, so he sold more than $10,000 in this week.
There is:
$588 - $400 = $188 left.
We know that if sells more than $10,000, he gets a commission of the 6% for the extra sales.
Then let's suppose that the extra is N.
The extra $188 must be equal to the 6% of N, then we get:
$188 = (6%/100%)*N
$188 = 0.06*N
$188/0.06 = N
$3,133.33
This means that he sold $3,133.33 more than $10,000
Then, in total, he sold $10,000 + $3,133.33 = $13,133.33
