The document contains notes from a math lesson on March 4th about working with percentages of quantities. It includes homework problems on finding remaining data after using a percentage and calculating new weight after losing percentages of weight over multiple periods. Examples are shown for finding the total surveyed if a percentage of people chose a certain option and calculating total calories from sugar if a percentage of total calories in an item is from sugar.

the month. What is the amount of data I have
remaining for this month?
2.) You are starting a new diet. In the three
months, you lose 10% of your body weight.
Then, in the next three months, you lose 5% of
