Name: __________________________ Mixture problems using two variables Yes, we do mix things in real life! The ability to picture the mixture story will give you the best opportunity to understand what is happening and achieve the correct results. Using a chart can additionally help organize the information from the problem. 1. The left bank is offering CD’s at 5%. The right bank is offering a money market account at 4%. If I have a total of $10,000 to invest in these accounts and want a return (accrued interest) on my money of $436 from both accounts at the end of one year , how much should I put into each account? Let C represent $$ you put into CD. Let M represent the $$ you put into the money market. Complete the chart below using information from the problem: Mixture problem Principal ($ invested) Rate (% as decimal) Time (yrs.) Interest ($ earned on investment) CD account C 0.05C Money market 0.04 0.04M Totals for the two bank accounts $10,000 Cannot be found by adding values above 1 The first column in the chart should contain information necessary to write one equation containing the two variables and the last column should show information to write another equation containing the two variables. Fill in the boxes below with the information from those columns to set up the system of equations: + = + = $$ put into CD account $$ put into money market Total $$ invested CD interest (at 5%) Money market interest (at 4%) Total interest Principal Rate Time =

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
