Question

alia uses these ingredients to make 12 potato scones:

• 1 cup self-raising flour
• 1 teaspoon butter
• 1\frac{1}{2} cup mashed potatoes
• \frac{1}{2} cup milk
• 1 pinch salt

alia used this recipe to make more scones.

if she needed 4\frac{1}{2} cups of mashed potato, how many scones did she make?

• 54
• 48
• 36
• 24

Explanation:

Determine the scaling factor for the recipe

$$ \text{Scaling Factor} = \frac{4\frac{1}{2}}{1\frac{1}{2}} = \frac{\frac{9}{2}}{\frac{3}{2}} = 3 $$

Calculate the total number of scones made

$$ \text{Total Scones} = 12 \times 3 = 36 $$

Answer:

• 54
• 48
• 36 (Correct answer)
• 24
