A small business owner is managing two equipment loans with a combined initial principal of $40,000. The first loan has an interest rate of 3.5%, and the second loan has an interest rate of 5.5%. The total interest paid across both loans last year was $1,800. Let $x$ represent the principal of the 3.5% loan and $y$ represent the principal of the 5.5% loan. Match each algebraic component to the real-world value it represents in this scenario.

A student is managing two different student loans with different interest rates and needs to determine the original principal for each loan. According to the seven-step problem-solving strategy, arrange the following actions in the correct order they should be performed.

When following the seven-step problem-solving strategy to organize a student loan problem into a mixture table, how should an interest rate of ${}6.9\%$ be recorded in the 'Rate' column to ensure the resulting system of equations is correct?

A business owner is managing two separate business loans with interest rates of ${}3\%$ and ${}5\%$. True or False: If the total interest paid for the year was 1,200 dollars, the equation used to represent this interest in a system of equations is ${}0.03x + 0.05y = 1{,}200$ (where $x$ and $y$ are the principal amounts of each loan).
