Equation representing the total number of coins:


Equation represents the total amount of money:

Answer 1

Let's define the variables:

- Let \( x \) represent the number of nickels.
- Let \( y \) represent the number of quarters.

### Equation representing the total number of coins:
Since Daisy has a total of 44 coins, we can write the first equation as:

\[
x + y = 44
\]

### Equation representing the total amount of money:
The value of the nickels (at $0.05 each) plus the value of the quarters (at $0.25 each) totals to $7.00. This gives us the second equation:

\[
0.05x + 0.25y = 7.00
\]

In summary, the equations are:

1. \( x + y = 44 \)
2. \( 0.05x + 0.25y = 7.00 \)
