Question

The bakery bought four bags of flour containing 3.5 kg each 475 g of flour are needed to make a batch of muffins and 0.65 kg is needed to make a loaf of bread if 4 batches of muffins and five loaves of bread are baked how much flour will be left give your answer in kilograms

Answer 1

The left out amount of floor is $\boxed{\bf8.85\,\,{\text{kilogram}}}$.

Further explanation:

The weight of one bag of flour is 3.5 kg.

The bakery bought 4 bags of flour.

Therefore, the total weight of 4 bags is calculated as follows:

$4\times\left({3.5\,\,{\text{kg}}}\right)=14\,\,{\text{kg}}$

The weight of flour needed for a batch of muffins is 0.475 kg.

Therefore, the weight of flour needed for 4 batches of muffins is calculated as follows:

$4\times\left({0.475\,\,{\text{kg}}} \right)=1.9\,\,{\text{kg}}$

The weight of flour needed for a loaf of bread is 0.65 kg.

Therefore, the weight of flour needed for 5 loaves of bread is calculated as follows:

$5\times\left( {0.65\,\,{\text{kg}}} \right)=3.25\,\,{\text{kg}}$

So, the total weight of floor used in the process of making muffins and loaves of bread is calculated as follows:

$3.25\,\,{\text{kg+}}1.9\,\,{\text{kg}}=5.15\,\,{\text{kg}}$

Now, the weight of floor that is left out in the bag is calculated as follows:

$14\,\,{\text{kg}}-5.15\,\,{\text{kg}}=8.85\,\,{\text{kg}}$

Thus, the left out amount of floor is $\boxed{\bf8.85\,\,{\text{kilogram}}}$.

Answer 2

First we have to find total mass of flour.
4*3.5kg=14kg
Now we are calculating how much flour we used for muffins
475g=0.475kg
0.475kg*4muffins=1.9kg
and now how much flour we used for bread
0.65kg*5bread=3.25kg
Finally we can subtract 1.9 and 3.25 from 14kg
14kg-1.9kg-3.25=8.85kg - its the answer
