at 4%
Transcript text: Colan invests $\$ 7300$ in two different accounts. The first account paid $6 \%$, the second account paid $4 \%$ in interest. At the end of the first year he had earned $\$ 396$ in interest. How much was in each account?
\$ $\square$ at $6 \%$
\$ $\square$ at 4\%
Solution
Solution Steps
To solve this problem, we need to set up a system of equations based on the information given. Let \( x \) be the amount invested at 6% and \( y \) be the amount invested at 4%. We know that the total investment is $7300, so \( x + y = 7300 \). The total interest earned is $396, so \( 0.06x + 0.04y = 396 \). We can solve this system of equations to find the values of \( x \) and \( y \).
Step 1: Set Up the Equations
Let \( x \) be the amount invested at 6% and \( y \) be the amount invested at 4%. We have the following equations based on the problem statement:
\( x + y = 7300 \)
\( 0.06x + 0.04y = 396 \)
Step 2: Solve the System of Equations
We can solve the system of equations to find the values of \( x \) and \( y \). From the solution, we find:
