Answer (2)

Calculate the total minutes: 22 × 31 = 682 minutes.
Calculate the cost per minute: 682 $102.30 ​ = $0.15 .
Melissa pays $0.15 per minute.
The answer is $0.15 ​ .

Explanation

Calculate total minutes First, we need to find the total number of minutes Melissa spent on her cell phone in January. We know she spent 22 minutes each day, and January has 31 days. To find the total minutes, we multiply the minutes per day by the number of days.

Total minutes calculation The total number of minutes is: 22 minutes/day × 31 days = 682 minutes So, Melissa used her cell phone for a total of 682 minutes in January.

Calculate cost per minute Next, we need to find out how much Melissa pays per minute. We know her total bill for January was $102.30, and she used 682 minutes. To find the cost per minute, we divide the total bill by the total number of minutes.

Cost per minute calculation The cost per minute is: 682 minutes $102.30 ​ = $0.15 per minute Therefore, Melissa pays $0.15 per minute.

Final Answer The question asks how much money Melissa pays per minute. We have calculated that Melissa pays $0.15 per minute. Therefore, the correct answer is A.


Examples
Understanding the cost per minute of cell phone usage can help you budget your monthly expenses. For example, if you know you typically use 500 minutes per month, you can calculate your expected bill by multiplying the minutes used by the cost per minute. This can also help you compare different cell phone plans to see which one offers the best rate per minute for your usage habits. This type of calculation is also useful in other areas, such as calculating the cost per unit of electricity or water usage.
