To solve this problem, we can set up a proportion with the given information:
18/34 = x/3
Cross-multiplying, we get:
34x = 18 * 3
34x = 54
Dividing both sides by 34, we find:
x = 54/34
x ≈ 1.6
Therefore, Luis will need approximately 1.6 cups of almonds. However, since we need to round to the nearest tenth, the answer is 1.6 rounded to 1 decimal place, which is 1.6.
The correct answer is 0.8 cups.
