Rachel sent or received 10,290 text messages in the month of September.
If each text message over the first 150 messages cost 8 cents, what was her texting bill? $126,750 Explain how you got your answer. I subtracted 10,290 by 150 then I divided 10,140 by 0.08 and I got 126,750.
Assuming that she slept 7 hours each day, what was the average number of text messages that passed through her phone each hour during her awake hours? Explain how you got your answer.
Your first answer doesn't make any sense. No one would pay 126 thousand dollars a month for texting.

To get the average number of text messages per hour during Rachel's awake hours, we need to first calculate the total number of awake hours in the month of September.
We know that there are 30 days in September, and assuming Rachel slept 7 hours each day, her awake hours per day would be 24 - 7 = 17 hours.
Therefore, the total number of awake hours in September would be 17 hours * 30 days = 510 hours.
Now, to calculate the average number of text messages per hour, we divide the total number of text messages (10,290) by the total number of awake hours (510):
Average number of text messages per hour = 10,290 / 510 = 20.2 (rounded to one decimal place)
So, the average number of text messages that passed through Rachel's phone each hour during her awake hours in September was approximately 20.2 text messages.
