So, Marguerite's bottle of iced tea contains two servings and has 64 grams of sugar. We want to know how many grams of sugar are there in each serving.
First, we need to write an equation:
2 • c = 64
The unknown number of grams of sugar per serving is c. To find it we use the opposite math operation; here, multiplication was used, so we will use division:
c = 64 / 2
c = 32
So, the amount of sugar per each serving is 32 grams
