Jocelyn borrowed 3.75 kg of flour from her grandmother to bake 3 batches of cookies and 2 cakes. each cookie recipe called for 225 grams of flour. each cake recipe needed 1.2 kg of flour after baking how much flour was Jocelyn able to return to her grandmother please explain thank you
Jocelyn borrowed 3.75kg which is equivalent to 3750grams Assuming a batch is one cookie recipe then: 3 batches * 225 grams = 675grams Jocelyn will use 675 grams of flour to bake 3 batches of cookies.
A cake recipe requires 1.2kg (equivalent to 1200grams). She wants to bake 2 cakes 2 cakes *1200grams = 2400 grams Jocelyn will use 2400 grams of flour to bake 2 cakes.
Add the total amount of flour she is going to use 2400 (for the cake) + 675grams (cookies) = 3075 She will use 3075 grams of flour in total.
Now take original borrowed amount from the amount she will use 3750-3075= 675
Therefore, Jocelyn will return 675 grams of flour back to her grandmother But obviously we must assume she doesn't spill any flour when she makes the cake but in this situation it doesn't ask for assumptions. So the answer should be 675 grams of flour.
