The weekly sales of Honolulu Red Oranges is given by q = 990 − 22p. Calculate the price elasticity of demand when the price is $
elena55 [62]

Answer:

E = -2. The demand is going down by 2% per 1% increase in price at that price level.

The price that gives a maximum revenue is $22.5. The maximum revenue is $9112.5

Step-by-step explanation:

The overall demand formula: Q = aP + b

Q = 990 - 22P

<u>Demand elasticity:</u>

At P = $30, the Q = 990 - 22×30 = 330. a = \frac{dQ}{dP} = -22

The formula for demand elasticity: E = \frac{dQ}{dP}×\frac{P}{Q}

Demand elasticity at $30: E = -22 × \frac{30}{330} = -2

So, The demand will be going down by 2% if 1% increase in price.

<u>Revenue:</u>

R = P×Q = P×(990 - 22P) = -22P² - 990P

R' = -44P - 990. The revenue is maximum when R' = 0

⇔0 = -44P - 990 ⇔ P = $22.5

At the P = $22.5, the Q = 990 - 22×22.5 = 495.

The maximum revenue = $22.5×495 = $11,137.5

Anja represents the inequality 4-g/8 &lt; - 15 with the phrase “the quotient of the difference of 4 and a number and 8 is at lea
scoundrel [369]

Answer:

Anja’s phrase should have ended with “less than –15”, not “at least –15”.

Step-by-step explanation:

Given the statement:

Anja represents the inequality \frac{4-g}{8}< -15

with the phrase “the quotient of the difference of 4 and a number and 8 is at least –15.”

Let the number be g.

“the quotient of the difference of 4 and a number and 8" translated to \frac{4-g}{8}

"at least" means \leq

then;

“the quotient of the difference of 4 and a number and 8 is at least –15.” translated to \frac{4-g}{8}\leq -15

Therefore, Anja’s phrase should have ended with “less than –15”, not “at least –15”.
