Let
x ----> the number of first class seats
y ----> the number of economy class seats
we know that
An aircraft has a maximum of 30 first class seats
so
An aircraft has a maximum of 220 economy seats
A flight will be cancelled if the money taken for the seats is less than $28,800.
so
therefore
Three inequalities that represent the situation are
Equations can be represented on graphs by plotting the corresponding x and y values. The graph of is option (B).
Given that:
First, we check the y intercept of
This is when
So, we have:
This point is represented as:
Next, check the equation when
So, we have:
This point is represented as:
From the list of given options (see attachment).
Only graph B has the and
on its curve.
Hence, option (B) is correct.
