To find out how much flour Jocelyn was able to return to her grandmother, we need to first calculate how much flour she used in total.
Each batch of cookies requires 225 grams of flour, and she baked 3 batches. So the total amount of flour used for the cookies is:
3 batches * 225 grams/batch = 675 grams
Each cake requires 1.2 kg of flour, and Jocelyn baked 2 cakes. So the total amount of flour used for the cakes is:
2 cakes * 1.2 kg/cake * 1000 grams/kg = 2400 grams
Now we add the amount of flour used for the cookies and the cakes to find the total:
675 grams + 2400 grams = 3075 grams
Since Jocelyn borrowed 3.75 kg of flour from her grandmother, which is equal to 3750 grams, we can subtract the total amount used from the amount borrowed to find the amount Jocelyn can return:
3750 grams - 3075 grams = 675 grams
Therefore, Jocelyn was able to return 675 grams of flour to her grandmother.
