Acharter airline finds that on its saturday flights from philadelphia to london, all 120 seats will be sold if the ticket price is $200. however, for each $3 increase in ticket price, the number of seats sold decreases by one.(a) find a formula for the number of seats sold if the ticket price is p dollars.(b) over a certain period, the number of seats sold for this flight ranged between 90 and 115. what was the corresponding range of ticket prices?

a)

b)

Step-by-step explanation:

For this case we can use a linear model to solve the problem.

s) Create an equation to express the increase on the price tickets and the number of seats sold

number of seats, if w analyze the info given the number of seats after increase the price is given by .

And let P the price for the ticket. So after the increase in ticket price the expression for the increase is P-200.

We have an additional info, for each increase of $3 the number of setas decrease 1. And the equation that gives to us the price change in terms of the increase of price is:

So then our linear equation is given by:

b) Over a certain period, the number of seats sold for this flight ranged between 90 and 115. What was the corresponding range of ticket prices?

So for this case we just need to replace the limits into the linear equation and see what we got:

So the corresponding range of ticket prices is:

answer: x
