Your goal this week is to be online for a mean of only 60 minutes per day. For the first six days of the week, you are online 70, 60, 65, 40, 78, and 62 minutes. What is the most time you can be online on the seventh day and still reach your goal?
60*7=420
70+60+65+40+78+62=375
420-375=45
You can only be online for 45 minutes on the seventh day to reach your goal
Answer: The most time you can be online on the seventh day is 45 hours.
Step-by-step explanation:

Mathematically speaking:
Now, we have to sum the amount of hours online of each day:
Finally, we have to subtract that number to the whole week number:
The most time you can be online on the seventh day is 45 hours.
