Answer 1

Explanation:

so, in total, Tosco sold 300kg of cheese in that week.

The full circle represents the whole amount of cheese sold, and the various sectors represent the relative quantities of the types of cheese inside that whole sold package.

to be precise, in this case the sectors show the percentage of each type of cheese (when 100% is the whole, the full circle).

Brie looks like is a quarter of the whole circle.

that means it is about 1/4 or then 100%/4 = 25% of the whole amount of sold cheese.

since the whole (100%) is 300kg, 1/4 of these 300kg is

300/4 = 75kg.

so, Tosco sold about 75kg of Brie in that week.
