Isolate "x" on one side of the algebraic equation by dividing the number that appears on the same side of the equation as part of "x."
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 
Answer:
6days
total cost-$66
additional days-5
Step-by-step explanation:
41+5(x-1)=31+7(x-1)
41+5x-5=31+7x-7
36+5x=24+7x
12=2x
x=6
36+30=66
Answer:
Replace x with −x and y with −y
to check if there is the x-axis, y-axis, or origin symmetry.
Not symmetric to the x-axis
Not symmetric to the y-axis
Not symmetric to the origin
but
Find the axis of symmetry-
x=1
Step-by-step explanation:
Answer:
x=6
Step-by-step explanation:
-6(6+5x)-4=-220
-36-30x-4=-220
-40-30x=-220
30x=-40-(-220)
30x=-40+220
30x=180
x=180/30
x=6
