Answer:

$\large \boxed{\sf \ \ \text{The maximum profit is \$94 per day.} \ \ }$

Step-by-step explanation:

Hello,

The coefficient in $x^2$ is negative.

So, there is a maximum at the vertex point which is

$x=-\dfrac{b}{2a}==\dfrac{-6}{-0.2}=\dfrac{6}{0.2}=30$

And then the maximum is f(30)=

$-0.1\cdot 30^2+6\cdot 30 +4=-90 +180+4=94$

So the maximum profit is 94 $ per day.

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

The surface area of the cylinder should be 1130.97. I found this by using the formula a=2πrh+2πr2.

Good luck my bud.
