9-35.

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?

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

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

Convert the fraction into a percent.

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

$\frac{3}{10}$

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

$30\%$ 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?

 Recipe A:$3$ cups Choc. Chips $2$ cups Peanuts $2$ cups Raisins $2$ cups Cashews $1$ cup of Coconut Recipe B:$5$ cups Choc. Chips $7$ cups Peanuts $4$ cups Raisins $2$ cups Cashews $1$ cups Coconuts $1$ cups Almonds Recipe C:$6$ cups Choc. Chips $7$ cups Peanuts $5$ cups Raisins $2$ cups Cashews $2$ cups Coconuts $3$ cups Almonds

• 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.
