Yin's cellphone plan costs $30 a month. She used 12.5 hours in May.

What was her cost per minute?

About how many call can she make?

Yin's average call lasted 3.25 minutes. How much did an average call cost?

bro its obv 69.420

1.2 because I have a big brain

To find Yin's cost per minute, we can divide the total monthly cost of $30 by the number of minutes she used in May.

Since Yin used 12.5 hours, we need to convert this to minutes. There are 60 minutes in an hour, so 12.5 hours is equal to 12.5 x 60 = 750 minutes.

Now, we can calculate the cost per minute by dividing the total monthly cost by the minutes used:
Cost per minute = $30 / 750 minutes = $0.04 per minute.

To estimate how many calls Yin can make, we need to divide the total number of minutes used in May (750) by the average call duration.

Number of calls = Total minutes used / Average call duration
Number of calls = 750 minutes / 3.25 minutes per call ≈ 230.77 calls

Therefore, Yin can make approximately 231 calls in a month with her cellphone plan.

To find the average cost of a call, we can multiply the average call duration by the cost per minute:

Average cost of a call = Average call duration x Cost per minute
Average cost of a call = 3.25 minutes x $0.04 per minute = $0.13 per call.

Therefore, an average call costs Yin $0.13.

I think is o.4 because yo have to divide

3000/(12.5*60) = 4 cents/min

now you can answer the questions.
