Let's denote the number of nickels as ( n ) and the number of quarters as ( q ).

We can set up a system of equations based on the given information:

- The total number of coins is 25: ( n + q = 25 )
- The total value of the coins is $3.45: 0.05n + 0.25q = 3.45 )

Now, we can solve this system of equations simultaneously to find the values of ( n ) and ( q ).

From equation 1, we can express ( n ) in terms of ( q ): ( n = 25 - q ).

Substitute this expression for ( n ) into equation 2:

[ 0.05(25 - q) + 0.25q = 3.45 ]

Now, solve for ( q ):

[ 1.25 - 0.05q + 0.25q = 3.45 ] [ 0.20q = 2.20 ] [ q = 11 ]

Now that we have found the number of quarters (( q = 11 )), we can find the number of nickels using equation 1:

[ n + 11 = 25 ] [ n = 25 - 11 ] [ n = 14 ]

Therefore, there are 14 nickels and 11 quarters in the bag.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
