a. The equation is s =    w

b.  cups of sugar will be needed to follow the recipe

Step-by-step explanation:

The equation of the direct proportional relation is y = k x, where

We can find the value of k by using the initial values of x and y

Let us use this rule to solve the question

∵ In the recipe for 1/2 cup of sugar for every 1 1/2 cups of water

→ That means the number of cups of sugar is in proportion to the

   number of cups of water

∵ s represents the number of cups of sugar

∵ w represents the number of cups of water

∴ s ∝ w ⇒ (∝ a sign of proportion)

∴ s = k w ⇒ k is the constant of proportionality

∵ s = and w =

Substitute the values of s and w in the equation above to find k

∵ = k ×

→ Multiply both sides by 2 to cancel the denominators

∴ 1 = 3 k

→ Divide both sides by 3 to find k

∴ = k

∴ The equation is s =    w ⇒ a.

→ We need to find the number of sugar cups for 4 1/4 cups of water

∵ w =

∵ s =    w

→ Substitute w by 5/4

∴ s = ×

∴ s =

∴    cups of sugar will be needed to follow the recipe ⇒ b.
