Final answer:
Luis will need approximately 1.6 cups of almonds.
Step-by-step explanation:
To find out how many cups of almonds Luis will need, we need to set up a proportion using the given information. The recipe calls for 18 cups of almonds for every 34 cups of chocolate chips. Since Luis is using 3 cups of chocolate chips, we can set up the proportion:
18 cups / 34 cups = X cups / 3 cups
Cross-multiply and solve for X:
18 * 3 = 34 * X
54 = 34X
Divide both sides by 34:
X = 54 / 34
X ≈ 1.588
Therefore, Luis will need approximately 1.6 cups of almonds.
