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.

    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:
    cups Choc. Chips
    cups Peanuts
    cups Raisins
    cups Cashews
    cup of Coconut

    Recipe B:
    cups Choc. Chips
    cups Peanuts
    cups Raisins
    cups Cashews

    Recipe C:
    cups Choc. Chips
    cups Peanuts
    cups Raisins
