To start, we know that this is a pie chart of all the minutes in a day. We're given percentages too, which means we'll have to multiply the minutes of a day by the percentage to see how many minutes are spent on extracurriculars.
So, to figure out how many minutes are in a day, we can do conversions:
Now we have how many minutes are in a single day!
So, we can now multiply these minutes by the percentage:
(We changed 8% to 8/100 to make the math a little clearer, but multiplying 3840 by 8% would give you the same number on a calculator!)
Therefore, Avery spends 307.2 minutes a day on extracurricular activities.
