Answer

\(\boxed{\text{Final Answer: Samantha invested \$8000 in the account with 6.2 \% loss and \$2000 in the account with 6.1 \% gain.}}\)

Steps

Step 1 :Let's denote the amount of money Samantha invested in the account with 6.2% loss as \(x\) and the amount she invested in the account with 6.1% gain as \(y\).

Step 2 :We know that the total amount of money she invested is \$10,000, so we have the first equation: \(x + y = 10000\).

Step 3 :After a year, the account with 6.2% loss lost 6.2% of \(x\), and the account with 6.1% gain gained 6.1% of \(y\). But in total, Samantha lost \$374. So we have the second equation: \(0.062x - 0.061y = 374\).

Step 4 :Now we have a system of two equations with two variables. We can solve this system to find the values of \(x\) and \(y\).

Step 5 :The solution to the system of equations is \(x = 8000\) and \(y = 2000\).

Step 6 :\(\boxed{\text{Final Answer: Samantha invested \$8000 in the account with 6.2 \% loss and \$2000 in the account with 6.1 \% gain.}}\)
