ANSWER:

1st option: 4x^4 + 27x

STEP-BY-STEP EXPLANATION:

We have that the earnings are given by the following functions:

[tex]\begin{gathered} S=x^4+16x \\ \\ W=3x^4+11x \end{gathered}[/tex]

If we add we get the following:

[tex]\begin{gathered} S+W=x^4+16x+3x^4+11x \\ \\ S+W=x^4+3x^4+16x+11x \\ \\ S+W=4x^4+27x \end{gathered}[/tex]

Therefore, the correct answer is the 1st option: 4x^4 + 27x
