Answer with Step-by-step explanation:
Since we have given that
q = 896-20p
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 
So for perimeter you need to find out the total of all the sides. To find out side AB, you make a triangle and find out the hypotenuse.
a=5 and b=6
a square= 25 b square= 36
25+36= 61
Square root of 61 is 7.81
So side AB is 7.81 ft
Now we need to find out side BC.
a=3 and b=4
a square is 9 and b square is 16.
9+16 is 25
Square root of 25 is 5
Side BC is 5 ft.
Because it's a rectangle, side CD will be 7.81 and side DA will be 5.
7.81*2+5*2= 25.62 ft
So the perimeter of the rectangle is 25.62 ft or C.
1 sq yrd = 9 sq. ft
so 30 sq. yards times 9 = 270 square feet
-"270 square feet"-
Answer:
78x
Step-by-step explanation:
8(3x+5)+14
8 x 8x+14
64x+14= 78x
