Answer:
x = -9.375
im not sure if i interpreted the times symbol right

step-by-step explanation:
2x + 30 = (30/10) • 5(2x + 3) + 87
2x + 30 = 3 • 10x + 15 + 87
2x + 30 = 105 • 10x
-2x -2x
30 = 105 • 8x
-105 -105
-75 = 8x
/8 /8
-9.375 = x ?

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

$x\leq 30$

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.

$240x+120y$

therefore

Three inequalities that represent the situation are

$x\leq 30$

$y\leq 220$

$240x+120y$
