<span><span>The price p and quantity x sold of a small flat screen television set obeys the demand equation below.
p= - .14x+280
:
a. How much should be charged for the television set if there are 60 television sets in stock? Round to nearest cent
p = -.14(60) + 280
p = -8.4 + 280
p = $271.60
:
b. What quantity x will maximize revenue?
Rev = qty * price
R(x) = x(-.14x+280)
R(x) -.14x^2 + 280x
The axis of symmetry is the qty for max revenue;x = -b/(2a)
x =
x = + 1000 tv's for max rev
:
What is the maximum revenue?
rev = -.14(1000^2) + 280(1000)
rev = -140000 + 280000
rev = $140,000

:
c. What price should be charged in order to maximize revenue?
p = -.14x + 280
p = -.14(1000) + 280
p = -140 + 280
p = $140</span><span>

Answer:
Step-by-step explanation:
Let n represent the number of friends who went to the movies with you.
Then ($12/ticket)n + $15 = $75. Solving for n, we get:
$75 - $15 $60
---------------- = ----------------- = 5 so a total of 5 friends went with you.
($12/ticket) ($12/ticket)
Answer:
correct ordered pair ( 4 , 1 ).
Step-by-step explanation:
Given : 3y=x-1 and x-2y=2.
To find : Use the elimination method to solve the system of equations.
Solution : We have given that
3y = x - 1 ------(1)
x - 2y = 2--------(2)
On subtracting x from both sides from equation 2.
-2y = -x + 2 --------(2)
Now adding equation 1 and 2
3y = x - 1 ------(1)
-2y = -x + 2 --------(2)
____________
y = 0 + 1
y = 1.
Now plug the value y = 1 in equation 1
3 (1) = x - 1.
3 = x - 1.
On adding both sides by 1
3 +1 = x
x = 4.
Pairs ( 4 , 1 )
Therefore, correct ordered pair ( 4 , 1 ).
