How to Find the % Vitamin C in each Drink:

1. Find the average number of drops of your trials for each drink.

2. Go up the Y-axis of your graph until you reach the average number of drops for that drink.

3. Move horizontally from that point across the graph until you reach your best fit line.

4. At the best fit line, drop straight down to find the percent of Vitamin C in that drink.

5. Record in a data table.

6. When you have found the Average % Vitamin C for each drink, create a new graph to compare how much Vitamin C each drink has!
