PLEASE ANSWER ASAP
The Pear company sells pPhones. The cost to manufacture x pPhones is
C(x)= -25x^2 + 49000x +21390 dollars (this includes overhead costs and production costs
for each pPhone). If the company sells x pPhones for the maximum price they can fetch, the
revenue function will be R(x)= -29x^2 + 129000x dollars.
How many pPhones should the Pear company produce and sell to maximimze profit? (Remember
that profit=revenue-cost)
x=
10,000 pPhones.
Step-by-step explanation:
The cost to manufacture x pPhones is given by the cost function:
And the revenue for selling x pPhones is given by the revenue function:
We want to determine the number of pPhones the Pear Company should sell to maximize profits.
First, we can find the profit function. Profit is given by:
Therefore:
Simplify:
Add. So, our profit function is:
Note that our profit function is a quadratic. The maximum point of a quadratic is always its vertex. So, we can find the vertex of the profit function.
The coordinate of the vertex is given by:
In this case, a = -4, b = 80000, and c = - 21390.
Therefore, the point at which profit is maximized is:
Therefore, in order to maximize profits, the Pear Company should sell exactly 10,000 phones.
Notes:
And the maximum profit will be:
22 dimes and 9 nickels
step-by-step explanation:
the answer would be d
straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.
b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.
