Step-by-step explanation:
<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>

200=10x divide by 10 and get 20=x. they make 20 quarts of ice cream every hour. multiply by 12, we get 240=12x. they can maek 240 quarts in 12 hours
Answer:
$167.50
$1507.50
$134
Step-by-step explanation:
Given that:
Cost of sound system = 1675
APR, = 12%
Down payment = 10%
Number of monthly payments = 12
r = 0.12 / 12 = 0.01
Amount of down-payment :
10% * cost of sound system
0.1 * 1675 = $167.50
Amount to be financed :
$1675 - $167.50
= $1507.50
Monthly repayment :
Using the relation :
A / {[(1+r)^n]-1}/[r(1+r)^n]
1507.5 / (1+0.01)^12-1)/(0.01(1+0.01)^12)
1507.50 / 0.1268/(0.01 * 1.1268)
1507.50 ÷ (0.1268/0.01126)
1507.50 ÷ 11.25
= $134
