A charter airline finds that on its Saturday flights from Philadelphia to London all 180 seats will be sold if the ticket price

Darina [25.2K]

Answer:

$S = -\dfrac{1}{3}P+\dfrac{740}{3}$

Step-by-step explanation:

Given that:

Number of seats sold is 180 with ticket price $200.

Number of seats decreases by one when the ticket price is increased by $3.

To find:

The formula for the number of seats sold (S) when the ticket price is P dollars.

Solution:

It is linear dependency of number of seats sold, S on ticket price, P.

$S\propto P$

It can be written as:

$S = kP+C$

Where $k$ is the constant of proportionality and

$C$ is a constant.

Now, putting the given values:

$180 = 200k +C ..... (1)$

$179 = 203k+C$ ...... (2)

Subtracting (1) from (2):

$3k = -1\\\Rightarrow k =-\dfrac{1}{3}$

Putting the value in (1):

$\Rightarrow C = 180+\dfrac{200}{3} = \dfrac{740}{3}$

Therefore the equation becomes:

$S = -\dfrac{1}{3}P+\dfrac{740}{3}$

Solve for x. 9x = 3x − 36

rusak2 [61]

Answer: $x=-6$

Step-by-step explanation:

In order to solve for "x", we must remember the following properties:

The Subtraction property of Equality states that:

If $a=b$ , then $a-c=b-c$

The Division property of Equality states that:

If $a=b$ , then $\frac{a}{c}=\frac{b}{c}$

Therefore, knowing these properties, we can solve for "x" to find its value.

First, we need to subtract $3x$ from both sides of the equation. Then:

$9x-(3x) = 3x - 36-(3x)\\\\6x=-36$

And finally, we can divide both sides of the equation by 6. Then we get:

$\frac{6x}{6}=\frac{-36}{6}\\\\x=-6$
