Question

My flip phone costs me $34 per month, and the cell phone company charges me $0.18 per minute I use the phone. If I need to keep my phone bill under $75 a month, how many minutes can I use without going over my budget?

Answer 1

Let x be the number of minutes you can use without going over your budget of $75.

Thus, the total cost of your phone bill can be represented as:
Total cost = $34 + $0.18x

Given that the total cost cannot exceed $75, we can set up the equation:
$34 + $0.18x ≤ $75

Subtracting $34 from both sides:
$0.18x ≤ $41

Dividing both sides by $0.18:
x ≤ 227.78

Therefore, you can use up to 227 minutes without going over your budget of $75.
