To find out how many cups of almonds Luis will need, we need to set up a proportion.
The ratio of almonds to chocolate chips is 18:34.
Let x be the number of cups of almonds Luis needs.
We can set up the proportion as:
18/34 = x/3
Cross-multiplying, we get:
34x = 3 * 18
34x = 54
Dividing by 34 on both sides:
x = 54/34
x = 1.588
Rounding to the nearest tenth, Luis will need approximately 1.6 cups of almonds.
So the correct answer is:
0.8 cup
