the long distance company that you use charges $5.00 per month and $0.10 per minute per call. If your current bill is $25.00, how many minutes did you use?
Current Bill $25.00
Monthly rate -$5.00
Sub Total $20.00
$20.00/ $.10 = 200 minutes
To find the number of minutes you used, we can set up an equation based on the given information.
Let's assume the number of minutes you used is represented by 'x'. According to the problem, the long-distance company charges $5.00 per month, which is a fixed fee, and $0.10 per minute per call. Therefore, the total bill can be calculated as follows:
Total Bill = Fixed Fee + (Variable Fee per Minute x Number of Minutes)
$25.00 = $5.00 + ($0.10 x x)
Now, let's solve the equation to find the value of 'x'.
$20.00 = $0.10x
Divide both sides of the equation by $0.10:
200 = x
Therefore, you used 200 minutes.
To determine the number of minutes used, we need to subtract the fixed monthly charge from the total bill, and then divide the remaining amount by the cost per minute.
1. Subtract the fixed monthly charge of $5.00 from the total bill of $25.00:
$25.00 - $5.00 = $20.00
2. Divide the remaining amount by the cost per minute of $0.10:
$20.00 / $0.10 = 200 minutes
Therefore, you used 200 minutes.
