Juan Carlos tiene 450 teléfonos móviles cada uno cuesta 30$y vienen 2 personas las 2 personas compran 3 teléfonos ¿cuantos dolares pagaron las 2personas?

$90

Step-by-step explanation:

Given that:

Number of mobile phones = 450

Cost per mobile phone = $30

Number of mobile phones purchased = 3

The total cost of 3 mobile phones = amount paid remaining :

(Cost per mobile phone * number of mobile phones purchased)

= $30 * 3

= $90

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
