The correct system of linear equations is \(n + q = 104\) and \(0.05n + 0.25q = 22\).
Explicar
## Step 1<br />The problem involves the creation of a system of linear equations based on the given information. The information provided is that Anatoliy has a combination of 104 nickels and quarters totaling $22.<br /><br />## Step 2<br />The first equation is derived from the total number of coins Anatoliy has. This is represented by the equation \(n + q = 104\), where \(n\) is the number of nickels and \(q\) is the number of quarters.<br /><br />## Step 3<br />The second equation is derived from the total value of the coins Anatoliy has. This is represented by the equation \(0.05n + 0.25q = 22\), where \(n\) is the number of nickels and \(q\) is the number of quarters.<br /><br />## Step 4<br />The other options do not accurately represent the given information. For example, the equation \(n + q = 22\) does not correctly represent the total number of coins, and the equation \(5n + 25q = 22\) does not correctly represent the total value of the coins.
