Question 1162049
.


The business should make 30*(1+4) = 30*5 = 150 dollars total earnings.



<pre>
    Assuming that all the business' earning is spend to compensate sellers . . . // (which is usually not the case . . . .

    But we can assume it for the sake getting the solution to the problem).
</pre>


Notice the difference between my statement and the John' statement:


<pre>
    I multiply $30  by 5 (five), while John assumes to multiply by 4.
