Answer:
$12,087,912.1
Step-by-step explanation:
is in scientific notation, to get this into normal number, we take the decimal point and move it "9" times to the right [whatever power of 10 we have, we move to right (if positive).] Then we fillup the rest with zeros.
So we have:

This is the revenue.
We do similar process for time:

This is the time , in minutes.
We want revenue PER minute, that means we divide the total revenue by total time, that would be:

The revenue earned per minute is $12,087,912.1
It would be: 8 (x + 3) - 2x
= 8x + 24 - 2x
= 6x + 24
In short, Your Answer would be 6x + 24
Hope this helps!
