<span>A
student divided the given number by 100 that resulted to 28.003 in his chart.
So what we are looking for this situation is the value of the number before it
was divided by 100.
To get the value, simply multiply the result by 100
=> 28.003 x 100
=> 2800.3
by dividing 100 to the given number, we
simply move the value to the right in a value of hundreds.

Answer:
In 1 hour the amount of water leaking from pool = 
gallon of water
Step-by-step explanation:
Given as :
The amount of Leaking of water from the pool = 
gallon
The time taken fro leaking gallon of water = 1 
gallon hour
Or The time taken fro leaking gallon of water = 
hour
∵ hour takes for leaking gallon of water
∴ In 1 hour the amount of water leaking from pool = 
Or, In 1 hour the amount of water leaking from pool = gallon of water Answer

Answer:
10,000 pPhones.
Step-by-step explanation:
The cost to manufacture <em>x</em> pPhones is given by the cost function:
And the revenue for selling <em>x</em> 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:
