Given:
Demand curve: q = (400-p)^2 / 100
where:
q = the number of copies the publisher can sell per week at $p
p = price of the copies
a) Find the price elasticity of demand when the price is set at $40 per copy
substitute p = $40
q = (400-40)^2 / 100
Therefore,
q = 1296

and the partial derivatives take on values of
So we end up with
Answer:
x = 10.3 in
Step-by-step explanation:
To find the value of a, use the area formula for a triangle. The formula is A = 1/2 *b*h. Here b = x and h= x. The formula becomes A = 1/2 *x². Substitute A = 53 and solve for x by using inverse operations.
A = 1/2x²
53 = 1/2x²
106 = x²
√106 = x
10.3 = x
