To make a dollar using 25 coins, you would need a combination of quarters, dimes, nickels, and pennies. One possible combination could be 3 quarters (0.75), 2 dimes (0.20), 0 nickels, and 0 pennies. This totals $1.00. Another combination could be 2 quarters, 1 dime, 0 nickels, and 20 pennies. Each quarter is worth 0.25, each dime is worth 0.10, each nickel is worth 0.05, and each penny is worth 0.01.
3 quarters+ 10 pennies+ 3 nickels= 1 dollar
