IM. MP1.PC.2020-2021 Question: 1-2 The number of loaves of bread that can be baked is proportional to the amount of flour
used. The table below models the amount of flour needed for a given number of loaves
of bread
What is the constant of proportionality that represents the amount of flour per loaf
of bread?
O 0.2
O 5.5
O 2.5
O 5
Loaves of Bread
Flour, in cups
2
12
20
15

Option (4)

Step-by-step explanation:

Number of loaves of bread (l) that can be baked is proportional to the amount of flour (f).

l ∝ f

l = kf

Where 'k' is the proportionality constant.

For loaves of bread = 4, amount of flour required = 20

Therefore, 20 = 4(k)

k =

k = 5

Therefore, proportionality constant will be,

k = 5

Option (4) will be the answer.

  answer:

  write 548 as 500 + 40 + 8. multiply each addend by 5. then add the three products to get 2,740.
