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

(9x + 17) +2 \times  ( 5x + 15 ) + (6x - 12) = 360 \\

9x + 17 + 10x + 30 + 6x - 12 = 360 \\

9x + 10x + 6x + 17 + 30 - 12 = 360 \\

Collect like terms

25x + 35 = 360

Subtract sides 35

25x + 35 - 35 = 360 - 35

25x = 325

Divide sides by 25

\frac{25x}{25}  =  \frac{325}{25}  \\

x = 13

Thus ;

RQ  \:  \: arc =2 \times (5x + 15)

RQ  \:  \: arc = 10x + 30

RQ  \:  \: arc = 10(13) + 30

RQ  \:  \: arc = 130 + 30

RQ \:  \:  arc = 160°
