Application: Investing
Apply Application: Investing concepts in Grade 10 math: model real-world scenarios using algebraic formulas and Saxon Algebra 2 problem-solving techniques.
Key Concepts
Set up variables for amounts in different accounts (e.g., $x, y, z$). Create equations for the total investment ($x+y+z=\text{Total}$), total interest earned ($0.05x+0.10y+0.13z=\text{Interest}$), and relationships between investments ($y = (x+z) 4000$).
You invest 15,000 dollars total. This gives you your first equation: $x+y+z=15000$. You earned 700 dollars in interest from accounts paying 4%, 6%, and 8%. Your interest equation is: $0.04x + 0.06y + 0.08z = 700$. The amount at 6% ($y$) is 2,000 dollars more than at 4% ($x$), so $y=x+2000$.
Solving systems isn't just for abstract math—it's for money! You can figure out exactly how much you invested in different stocks or savings accounts. Each piece of information, like your total investment or the interest you earned, becomes one of the equations you need to solve to find out exactly where your money went.
