Hey there!
Your question states:
<span>John's monthly paycheck consists of $4000 plus a 9% commission on all of his sales. During one month, John earned $11,650. What were his sales during that month?
</span>
We don't want to 9% to really trick us.
We just do 11,650 - 4,000 = 7,650.
Now, we can adjust everything.
That
9% of the commission on the sales was worth
. . . 7,650
Your correct and clarified answer would be
. . .

Hope this helps.

To get the inverse
of any function f(x) [ just make sure that it passes the horizontal line test]
follow the steps:
- Solve for x, i.e separate x in one side
and the other terms in the other side, included f(x).
- Swap x and f(x).
- The result is the inverse of the original
function
.

Apply that on your function
Can you show the multiple choice one
To find the median you have to put all the numbers in order from smallest to largest and find the one that's in the middle.
All of the numbers listed are already in order, and the one that lies in the middle is 40. So the answer is 40.
