To determine how many cups of almonds Luis needs when using 3 cups of chocolate chips, we can set up a proportion based on the recipe's ratios.

The recipe states:

  • 18 cups of almonds for every 34 cups of chocolate chips.

We can express this as:

\[ \frac{18 \text{ cups of almonds}}{34 \text{ cups of chocolate chips}} = \frac{x \text{ cups of almonds}}{3 \text{ cups of chocolate chips}} \]

Now, we can cross multiply to solve for \( x \):

\[ 18 \cdot 3 = 34 \cdot x \]

\[ 54 = 34x \]

Now, divide both sides by 34:

\[ x = \frac{54}{34} \approx 1.5882 \]

Now, rounding to the nearest tenth:

\[ x \approx 1.6 \]

It looks like there was a mistake in the initial options you provided since none of the answers match. If we round \( 1.6 \) to the nearest option, the appropriate response would be approximately:

1.6 cups

However, keep in mind that none of the options you mentioned provided this as an answer. Can you please review the choices given?
