Biography

I have sincerely enjoyed tutoring in an official role, as well as unofficially having tutored and aided my fellow classmates better understand the materials.
Most recently, I privately tutored a Community College student and helped them to pass their Calculus course. We met virtually through Skype or Google Chats. I have also previously worked with an elementary school child and aided them in all their subjects (Math, English, Science). I charged no fee, and I provided any necessary materials in both cases.

Maximum profit: An automobile manufacturer can produce up to 300 cars per day. The profit made from the sale of these vehicles can be modeled by the function $P(x)=-10 x^{2}+3500 x-66,000$ where $P(x)$ is the profit in dollars and $x$ is the number of automobiles made and sold. Based on this model:
a. Find the $y$ -intercept and explain what it means in this context.
b. Find the $x$ -intercepts and explain what they mean in this context.
c. How many cars should be made and sold to maximize profit?
d. What is the maximum profit?

Maximum profit: The profit for a manufacturer of collectible grandfather clocks is given by the function shown here, where $P(x)$ is the profit in dollars and $x$ is the number of clocks made and sold. Answer the following questions based on this model: $P(x)=-1.6 x^{2}+240 x-375$
a. Find the $y$ -intercept and explain what it means in this context.
b. Find the $x$ -intercepts and explain what they mean in this context.
c. How many clocks should be made and sold to maximize profit?
d. What is the maximum profit?

The cost to produce bottled spring water is given by $C(x)=16 x-63,$ where $x$ is the number of thousands of bottles. The total income (revenue) from the sale of these bottles is given by the function $R(x)=-x^{2}+326 x-7463$. since profit $=$ revenue $-$ cost, the profit function must be $P(x)=-x^{2}+310 x-7400$ (verify).
how many bottles sold will produce the maximum profit? What is the maximum profit?
