Question 1 Consider the demand function:
Q = -3p2 + 2p + 1970
=
where q = quantity, p = price
1
a) Find Total Revenue as a function of p.
(Hint: Do not attempt to find Total Revenue as a function of q, as to do so
requires use of the inverse demand function which is difficult to find in this case.

yes

step-by-step explanation:

yes

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
