The weekly sales of Honolulu Red Oranges is given by q = 896 − 20p.(A) Calculate the price elasticity of demand when the price i

vitfil [10]

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

$e=-\dfrac{dq}{dp}\times \dfrac{p}{q}\\\\e=-(-20)\times \dfrac{32}{896-20p}\\\\e=\dfrac{20\times 32}{896-20p}\\\\e=\dfrac{640}{896-20p}\\\\e=\dfrac{640}{896-640}\\\\e=\dfrac{640}{256}=2.5$

(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.

$R=pq\\\\R=p(896-20p)\\\\R=896p-20p^2$

We first find the first derivative:

$R'(p)=896-400p$

So, it becomes,

$896-40p=0\\\\40p=896\\\\p=\dfrac{896}{40}=\$22.4$

R=-40<0, so, it will give maximum revenue.

(D) Find this maximum revenue.

Maximum revenue would be $R=pq\\\\R=22.4(896-20\times 22.4)\\\\R=\$10035.2$

Mr. Ledger buys a box of 24 donuts for a lesson in his math class about circumference. Write an equation for the number of donut

creativ13 [48]

<span>An equation for the number of donuts y that are left at the end of the day when x donuts are being used during the day is y=24-x. You would subtract x, the number of donuts being used from 24, the total amount of donuts. To get your y.</span>

aleksley [76]

Answer: (x−3)(x+7)

=(x+−3)(x+7)

=(x)(x)+(x)(7)+(−3)(x)+(−3)(7)

=x^2+7x−3x−21

=x^2+4x−21
