Helena needs 3.5 cups of flour per loaf of bread and 2.5 cups of flour per batch of muffins. she also needs 0.75 cup of sugar per loaf of bread and 0.75 cup of sugar per batch of muffins. helena has 17 cups of flour and 4.5 cups of sugar available for baking. which combination of loaves of bread and batches of muffins could helena bake?

Helen can make 2 loaves of bread and 4 batches of muffins.

Step-by-step explanation:

Let x be the number of loaves of bread

Let y be the number of batches of muffins

As per the given requirement of flour, the equation becomes:

  .......(1)

As per the given requirement of sugar, the equation becomes:

 .....(2)

Multiplying equation (1) with 0.3 and subtracting (2) from (1)

now subtracting (2) from this we get

=>

So, x = 2

And as ; so substituting x = 2 here we get

So, y = 4

Hence, there will be 2 loaves of bread and 4 batches of muffins.

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
