PLEASE HELP ASAP I WILL GIVE 20 POINTS 1. Add 3 level scoops of mini chocolate chips and 1 level scoop of raisins to Container If each scoop has the same number of items, what percent of the items in Container are mini chocolate chips?
(This value is known as the percent concentration of chips.) Explain how you decided.
Label the container appropriately

2. Add 2 scoops of mini chocolate chips and 3 scoops of raisins to Container 2. What is the
percent concentration of mini chocolate chips? Explain how you decided. Label the
container appropriately. Stir the chips and raisins in each container to ensure that the
chips and raisins are evenly mixed.

3. Add one scoop from Container 1 and two scoops from Container 2 to Container 3.
Estimate the percent of mini chocolate chips in Container 3. Describe how you
estimated the percent concentration.

4. Stir the chips and raisins in Container 3 so that they are evenly mixed.
a. Remove a sample of chips & raisins from Container 3, and count the number of
chips and raisins.
Mini Chips: Raisins:

b. Calculate the percent concentration of mini chocolate chips in the sample. How
closely does the mix in your sample match your estimate from Question 3?

c. If your answers to Question 3 and 4a are very far off, which answer do you think
is it more accurate? Explain why you think that.

6. Develop a strategy to calculate the percent concentration of mini chocolate chips in
Container 3. Use this strategy to determine the percent concentration if 1 scoop of a
75% mixture of mini chips is combined with 2 scoops of a 40% mixture of mini chips. If
you do not get a reasonable answer, either refine your strategy or check your
calculations. Explain your strategy here.

7. Test your word formula with another mixture. Separate the chips and raisins and return
them to their original containers. Make up the new problem by deciding how many
scoops of each to put into Containers 1 and 2. Then, determine the percent
concentrations of mini chocolate chips in each container. Finally, decide how many
scoops from Containers 1 and 2 to combine in Container 3 for the final mix. (At each
step, stir so they are evenly distributed.)
a. Calculate the percent concentration of mini chips in Container 3 by taking a
sample and counting the number of chips and raisins.

b. Use your word formula from Question 6 to calculate the percent concentration
of mini chips in Container 3.

c. If your word formula did not yield similar results as the experiment, check your
work and correct the formula as needed.

8. Write your formula and a description of how to use the formula for solving other
mixture problems.
