To find the number of cups of almonds needed, we can use a proportion.
Let x be the number of cups of almonds needed.
According to the recipe, there are 18 cups of almonds for every 34 cups of chocolate chips.
Thus, we can set up the proportion:
18/34 = x/3
Cross-multiplying, we get:
34x = 18 * 3
34x = 54
Dividing both sides by 34, we get:
x = 54/34 ≈ 1.6
Rounding to the nearest tenth, we get x ≈ 1.6 ≈ 1.5
Therefore, Luis will need approximately 1.5 cups of almonds.
The correct answer is 0.5 cup.
