An aircraft has a maximum of 30 first class seats and 220 economy seats.

Sidana [21]

Answer:

$x\leq 30$

$y\leq 220$

$240x+120y$

Step-by-step explanation:

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

$x\leq 30$

An aircraft has a maximum of 220 economy seats

$y\leq 220$

A flight will be cancelled if the money taken for the seats is less than $28,800.

so

$240x+120y$

therefore

Three inequalities that represent the situation are

$x\leq 30$

$y\leq 220$

$240x+120y$
