A muffin recipe calls for \(\frac{2}{5}\) tablespoon of vanilla extract to make 6 muffins. Arthur is making 18 muffins. How much vanilla extract does he need?
Answer (2)
x − v ani ll a e x t r a c t F ro m p ro p or t i o n : 5 2 − 6 x − 18 6 x = 5 2 ⋅ 18 6 x = 5 36 ∣ ⋅ 6 1 x = 5 36 ⋅ 6 1 x = 5 6 = 1 5 1 He n ee d 1 5 1 v ani ll a e x t r a c t .
Arthur needs 1 5 1 tablespoons of vanilla extract to make 18 muffins, based on the original recipe which requires 5 2 tablespoons for 6 muffins. We calculated this by finding the amount needed per muffin and then multiplying by the total number of muffins. Thus, for 18 muffins, it amounts to 5 6 tablespoons, which is 1 5 1 tablespoons.
