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
First we have to find total mass of flour.
43.5kg=14kg
Now we are calculating how much flour we used for muffins
475g=0.475kg
0.475kg4muffins=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
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 \(\boxed{\bf8.85\,\,{\text{kilogram}}}\).
