As a Cash Office Supervisor trainee, you are learning the standard procedure for resolving cash drawer discrepancies involving mixed currency. Recalling the standard problem-solving strategy, arrange the following steps in the correct order to set up and solve a coin mixture application using a system of equations.

As a retail supervisor, you are training a new cashier to balance their register. When setting up a system of equations to solve a discrepancy involving nickels ($n$) and dimes ($d$), which equation correctly represents a total value of ${}2.75$ based on the standard problem-solving strategy?

In your role as a Petty Cash Auditor, you are verifying the mathematical logic of an automated spreadsheet used to reconcile coin discrepancies. Match each component of the value equation ${}0.05n + 0.10d = 8.10$ to the specific financial data point it represents in your audit.

In a professional cash-handling scenario, when setting up a system of equations for a coin mixture problem where $n$ represents the number of nickels and $d$ represents the number of dimes, the equation $n + d = 5.50$ is the correct way to represent that the total monetary value of the collection is $5.50.
