I needed to determine the derivative of e^3x(cos4x+4sin4x)

so far i have

f'(x)= 3e^3x(cos4x+4sin4x) + e^3x(16cos4x-4sin4x)

How can i simplfy it so i end up with an answer of
f'(x)= e^3x(19cos4x+8sin4x)<--- this is the final answer...I need the steps in between!

QUESTION:
How would you arrange the steps in order in a continuous, twice differentiable function when finding its inflection point?

THE CHOICES IN RANDOM ORDER:

A = evaluate the function at the points where the second derivate is zero
B = analyze the sign changes of the second derivative
C = find the zeors of the second derivative
D = find the second derivative
E = find the first derivative

Whats the proper order A through E?

Thanks!

How would I solve this. It'd be helpful if you showed your work.

A bus company has 4000 passengers daily,each paying a fare of 2$. For each 0.15$ increase the company estimates it will lose 40 passengers. If the company needs to take in 10 450 per day to stay in business what fare should be charged.
