Answer:
(a) $6,412.12
(b) 6624.
Step-by-step explanation:
We have been given the total cost function for a product is , where x is the number of units produced.
(a) To find the total cost of producing 400 units, we will substitute in our given formula.
Therefore, the total cost of producing 400 units is $6,412.12.
(b) To find the number of units produced with total costs of $8500, we will substitute in our given formula.
Switching sides:
Subtract 1900 from both sides:
Now, we will divide both sides of our equation by 750.
Using logarithm definition, we will get:
Therefore, producing 6624 units will give total costs of $8500.
It would be 1.66 because you divide 15 by 9
Answer:
10%
Explanation :
To solve the problem, we should know the definition of annual simple interest. We have,
Simple Interest (I) = P×R×t100
Where, P= principal amount
R = simple interest annual rate
t = time period of the annual simple interest
Here, we have R = 10% and have to calculate t for the sum of the money (that is P) to double.
