1h 15minutes, I converted each time into fractions, 2hours to
and the 8hour to
, this means, painter #1 finishes 1/2 of the project in 1 hour, and paither #2 finishes 1/8 of project in 1 hour, now when we make each fraction out of 2 hours, so
and
, we add them and get
, then as mixed number, 1 1/4 which is 1 hour and 15min<em>(1/4 of a hour)</em>
I believe im right.
remember, x is on the left side for x- intercept while Y is on the right but you put it on the left for the Y intercept.
example
x intercept is (-5, 0, 5)

<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>
