The polynomial [tex]s^3 - 70s^2 + 1500s - 10{,}800[/tex] models the profit a company makes on selling an item at a price [tex]s[/tex]. A second item sold at the same price brings in a profit of [tex]s^3 - 30s^2 + 450s - 5000[/tex]. Write a polynomial that expresses the total profit from the sale of both items.
A. [tex]2s^3 - 100s^2 + 1950s - 15{,}800[/tex]
B. [tex]2s^3 - 100s^2 + 1950s + 15{,}800[/tex]
C. [tex]2s^3 + 100s^2 + 1950s - 15{,}800[/tex]
D. [tex]-40s^2 + 1050s - 5{,}800[/tex]
