Examine the snack-mix recipes described below.

1. Calculate the portion of each mix below that is chocolate chips, expressing your answer as a percent. Which recipe has the greatest concentration of chocolate chips?

   Step 1(a):

   For Recipe A, find the total number of cups in the recipe.

   Step 2(a):

   Next, write a fraction expressing the portion that is chocolate chips.

   Step 3(a):

   Convert the fraction into a percent.

   $3 \text{ cups} + 2 \text{ cups} + 2 \text{ cups} + 2 \text{ cups} + 1 \text{ cup} = 10 \text{ cups}$

   $\frac{3}{10}$

   $\frac{3}{10}=\frac{30}{100}=30\%$

   Partial Answer (a):

   $30\%$ of Recipe A is chocolate chips.
   Repeat the above steps for Recipe B and Recipe C, then determine which has the highest percent of chocolate chips.

2. Calculate the portion of each mix that is peanuts, again expressing your answer as a percent. Which recipe has the greatest concentration of peanuts?

   Hint (b):

   This problem is very similar to part (a), and you have already found the total number of cups in each recipe.
   For each recipe, express the portion first as a fraction and then convert the fraction to a percent.
