Carlo wants to buy a $425 computer. He earns $7 per hour at his job. Write an inequality to express this situation and than identify what x stands for.
7 x >/= 425
x is hours he has to work to make at least enough.
ok thanks
To write an inequality expressing this situation, we can set up the following equation:
7x ≥ 425
In this equation, x represents the number of hours Carlo needs to work in order to earn enough money to buy the $425 computer. Multiplying his hourly wage of $7 by the number of hours he works (x) should be greater than or equal to $425.
