Answer:
Marginal revenue = R'(Q) = -0.6 Q + 221
Average revenue = -0.3 Q + 221
Step-by-step explanation:
As per the question,
Functions associated with the demand function P= -0.3 Q + 221, where Q is the demand.
Now,
As we know that the,
Marginal revenue is the derivative of the revenue function, R(x), which is equals the number of items sold,
Therefore,
R(Q) = Q × ( -0.3Q + 221) = -0.3 Q² + 221 Q
∴ Marginal revenue = R'(Q) = -0.6 Q + 221
Now,
Average revenue (AR) is defined as the ratio of the total revenue by the number of units sold that is revenue per unit of output sold.

Where Total Revenue (TR) equals quantity of output multiplied by price per unit.
TR = Price (P) × Total output (Q) = (-0.3Q + 221) × Q = -0.3 Q² + 221 Q


∴ Average revenue = -0.3Q + 221
Direct variation is y=kx
indirect variation is y=k/x
if we can get it into that form, then it is
5x+6x=1
6y=-5x+1
y=(-5/6)x+1/6
yes
-4x+9y=4
9y=4x+4
y=(4/9)x+4/8
yes
Answer:
1 1/4 cups of flour
Step-by-step explanation:
First find the amount for 1 serving.
So you divide the amount of 1 1/2 or 1.50 by 4
1.50/4=.375
Now do .375*7= 2.625 cups of flour
Now you need to subtract the amount you already have which is 4 cups.
2.625-1.50= 1 1/4 cups of flour is what you need left
We determine the number of cubic yards that James need to order by converting the unit of measurement given in feet to yards. Every yard is composed of 3 feet. Thus, the solution would be,
(180 ft)³ x (1 yd/ 3ft)³ = 6.67 yd³
Thus, James will have to order 6.67 yd³.
