Answer:

Explanation:

David uses 1 table spoon of sugar for every 1.25 cups of water to prepare lemonade.

Therefore, Number of table spoons of sugar required (S) ∝ Cups of water required (w)

⇒ S ∝ w

⇒ S = kw

⇒ k =
(S)/(w)

⇒ k =
(1)/(1.25) = 0.8

So the formula to calculate the amount of water will be,

S = 0.8w

⇒ w =
(S)/(0.8)

where k = proportionality constant

Now we can complete the table with the help of the formula.

Sugar (tbsp) Water (cups)

1 1.25

7 8.75

3 3.75

5 6.25
