Answer:
Sharla has more, by $2000.
Step-by-step explanation:
Company B has 30000+2400x.
Company C has 36000+2000x.
Since we know x is equal to 10, because they have been working from the last ten years, we plug in 10 at where the x has been.
Company B: 30000+2400(10)
Company C: 36000+2000(10)
Let's first solve for B.
30000+2400(10)= 30000+24000=54000.
So, Paul earned $54000.
Next, Let's solve for C.
36000+2000(10)= 36000+20000=56000.
Sharla earned $56000.
It is obvious that sharla has more, so we will find the difference between the earnings of two companies.
56000-54000=2000.
So, Sharla has more earnings, with $2000 more than Paul.
