Given that,
Alonzo is $120 in debt. He makes $15 per hour. He wants to have at least $75 left over after he has paid off his debt.
To find,
The inequality and the solution.
Solution,
Let he make $x per hour. Here, $120 is fixed. $15 is added per hour.
ATQ,
[tex]120 + 15x\ge 75[/tex]
For atleast, we use [tex]\ge[/tex].
Subtract 120 from both sides.
[tex]120 + 15x-120\ge 75-120\\\\15x\ge -45\\\\x\ge -3[/tex]
So, the required answer is greater than -3.
