Understanding the Problem

A total of 22 dimes and nickels have a value of $\$1.90$. If $d$ represents the number of dimes and $n$ represents the number of nickels, we need to determine which system of equations models this situation.

The Value of Dimes and Nickels

Each dime is worth $\$0.10$, and each nickel is worth $\$0.05$. We can use these values to create a system of equations that represents the given situation.

System of Equations

Let's consider the following system of equations:

• The total number of coins is 22, so we can write the equation: $d + n = 22$
• The total value of the coins is $\$1.90$, so we can write the equation: $0.10d + 0.05n = 1.90$
