Answer:
Selling 40 items will produce a maximum profit.
Step-by-step explanation:
We need to use First and Second Derivative Tests on profit function to determine how many items will lead to maximum profit. Let , where is the profit for a product, measured in US dollars, and is the amount of items, dimensionless.
First we derive the profit function and equalize it to zero:
(Eq. 1)
Roots are found by Quadratic Formula:
and
Only the first root may offer a realistic solution. The second derivative of the profit function is found and evaluated at first root. That is:
(Eq. 2)
(Absolute maximum)
Therefore, selling 40 items will produce a maximum profit.
By using variables to represent items and operations to represent the relationship between the variables.
Answer:
3/10
Step-by-step explanation:
1/100 of a metre, as 100cm make 1m
First, find out how much money it cost per 1 lb of apples.
Divide $4.8/ 6 lbs
$0.8/ 1 lbs
Multiply amount per pound by cost
0.8 * 10 = 8
$8.00 for 10 lb bag of apples.
