Answer:
Constant of proportionality, k = 21
Step-by-step explanation:
We are given the following in the question:
The amount of flour required is directly proportional to the number loaf of breads made.
Let w be the weight of flour and n be the number of loaf of breads.
Thus, we can write,
where k is the constant of proportionality.
21 ounces of flour is required to make 1 loaf of bread.
Putting these values, we get,
Thus, the equation giving relation between weight of bread and number of loafs of bread is
Answer:x=-14y=174
y=3x+5,y=-x+4
3x+5=-x+4

$84.42........... hope this helps you :)
-450 + 12x.....this is basically stating that the sewing machine and some fabric cost him $ 450....and he is selling each blanket for $ 12 a piece.
The total amount he earns is 12x....where x is the number of blankets
