Answer:

$320000

Step-by-step explanation:

Given that on a certain route, an airline carries 5000 passengers per​ month, each paying ​$60.

A market survey indicates that for each​ $1 increase in the ticket​ price, the airline will lose 50 passengers

Let 1 dollar be increased x times (say)

Original revenue = 60(5000) =300000

After increase of x dollars, revenue would be a function of x

R(x) = R(x) =(60+x) (5000-50x)\\\\R(x) = 300000+2000x-50x^2

Use derivative test to find maximum

R(x) = 300000+2000x-50x^2\\R'(x) = 2000-100x\\R"(x) = -100

So maximum when I derivative is 0

i.e. when x = 20

Maximum revenue

R(20) = (60+20)(5000-1000)\\= 320000

She had $3000. She spend 40% of the money in smart TV and 15% of the remainder on Game Set. (a) What % of the money had she left
Dovator [93]

Answer: She had left 54% of the money which is $1620.

Step-by-step explanation:

40% of $3000 = $1200

15% of $1200 = $180

$3000 - ($1200 + $180)

$3000 - $1380 = $1620

$1620 is the money she had left.

$1620 is 54% of $3000

She had 54% left of the money.

Hope that helped~!

Enter an inequality that represents the graph in the box.
ANTONII [103]

The inequality that represents the graph in the box  is

y>-3x+6

Given :

The graph of the linear inequality

Lets pick two points from the graph to frame the linear equation

Slope intercept form of the equation is

y=mx+b

Where m is the slope and b is the y intercept

y intercept is (0,6) from the graph

so b=6

Now we find out slope m  using formula

Pick two points (0,6) and (2,0)

slope = \frac{y_2-y_1}{x_2-x_1} \\m=\frac{0-6}{2-0} =-3

m=-3

So the equation is y=-3x+6

Now we check the inequality sign by testing any point on shaded area

lets pick (4,0)

lets plug in 4 for x  and 0 for y

y=-3x+6\\0=-3(4)+6\\\\0=-6\\0>-6

The inequality for the given graph is

y>-3x+6

we cannot use >= sign because we have dotted lines

The equation
ra1l [238]
<h2>Explanation:</h2>

Let's use a trial and improvement method to find this solution.

Step 1. Let's choose x = 8.5

Substituting into the equation:

(8.5)^2+ 3(8.5) - 94=0? \\ \\ 72.25+25.5-94=0? \\ \\ 3.75\neq 0

Step 2. Let's choose x = 8.4

Substituting into the equation:

(8.4)^2+ 3(8.4) - 94=0? \\ \\ 70.56+25.2-94=0? \\ \\ 1.76\neq 0

Step 3. Let's choose x = 8.3

Substituting into the equation:

(8.3)^2+ 3(8.3) - 94=0? \\ \\ 68.89+24.9-94=0? \\ \\ -0.21\neq 0

Since the sign of the equation changes from positive to negative when evaluating from 8.4 to 8.3, then x = 8.3 seems to be a reasonable value. Finally, the solution to 1 decimal place is:

x=8.3
