Answer:
The correct answer is a) R = = - 
+ 30x; b) $ 1120; c) Maximum quantity is 75 units with maximum revenue being $1125; d) p = $15.
Step-by-step explanation:
Demand equation: p = - x + 30 , 0 
x 150 ; where p is the price of the product and x is the quantity sold.
a) Revenue function by the problem is given to be R= p × x = - + 30x.
b) Revenue at x = 70 is given by 2100 - 980 = $ 1120.
c) For maximizing the R we differentiate it with respect to x and equate it to zero.
⇒ - 
x + 30 =0
⇒ x = 75.
As the second order derivative is negative at this point, this is the value of x that maximizes the revenue.
Maximum Revenue is at x = 75 and is equal to $1125.
d) Price charged by the company for maximum revenue is $15.
Answer
148cm^2
Explanation
A cuboid has equal width and length as it’s base is a square. So w or l = root 30
Since the volume of a cuboid is
Length • width • height
And we know length and width when multiplied are 30
30 • height = 120
Therefore height = 4
Now for surface area it’s
2 • h • l + 2 • h • w + 2 • l • w
2 • 4 • root 30 + 2 • 4 • root30 + 2 • 30 = 60 + 16root30 = 148~cm^2
