Ling earns $8 per hour working at the zoo. Write and solve an inequality that can be used to find how many hours she must work in a week to earn at least $120. Interpret the solution.

Respuesta :

Answer:

Ling should atleast work 15 hours a week to earn $120.

Step-by-step explanation:

Ling earn per hour = $8

Let the number of hours she worked to be x.

Now, inequality =  

[tex]8x \geq 120[/tex]

Dividing both side by 8.

[tex]\dfrac{8x}{8} \geq \dfrac{120}{8}[/tex]

[tex]x \geq 15[/tex]

Hence, Ling should atleast work 15 hours a week to earn $120.
