p = $32
.(A) Calculate the price elasticity of demand
As we know that
(B) The demand is going down with increase in 15 increase in price at that price level, as we know that there is inverse relationship between price and quantity demanded.
(C) Also, calculate the price that gives a maximum weekly revenue.
We first find the first derivative:
So, it becomes,
R=-40<0, so, it will give maximum revenue.
(D) Find this maximum revenue.
Maximum revenue would be 
Answer:
3.5 years
Step-by-step explanation:
Each year, Louis earned
$1500×0.035 = $52.50
in interest.
The amount of interest that had been credited to his account at the time of withdrawal was ...
$1683.75 -1500.00 = $183.75
Then the length of time the money had been in the account was ...
$183.75/($52.50/yr) = 3.5 yr
_____
<em>Comment on the problem</em>
We have assumed the account earned simple interest. Given the neatness of the answer, we believe that to be a correct assumption.
Answer:
The equation is TRUE.
Step-by-step explanation:
To solve the given equation:
You need to find the value of the variable "d". You can apply this procedure:
- Multiply both sides of the equation by 9:
- Divide both sides of the equation by 5:
Check the solution substituting the value of "d" into the equation and evaluating:
