Oh, dude, you're really making me do math right now? Alright, fine. So, technically, you could have 9 dimes, because 9 times 10 cents equals a dollar. But seriously, who even carries around that many coins these days? Just use a card, man.
To make a dollar using 9 coins, you would need 5 pennies, 1 nickel, and 3 dimes. This totals to 9 coins in total: 5 pennies (5 cents), 1 nickel (5 cents), and 3 dimes (10 cents each). The sum of these coins would equal $1.
"9" nickels, "3" dimes and "1" quarter
A half dollar (50-cent piece), 7 nickels, and a penny.
2 quarters, 6 nickels and 20 pennies make a dollar. Also, 8 dimes and 20 pennies make a dollar. Also, 4 dimes, 9 nickels and 15 pennies make a dollar. Also, 18 nickels and 10 pennies make a dollar. Also, 3 quarter and 25 pennies make a dollar.
3 1 1 1 1 1 1 The drawing above, if it is preserved by the formatting, illustrates how. For the first row, put on 4 coins in a row. Stack two additional coins on top of one of the coins. For the second row, make it perpendicular to the first row, and overlapping the stack of 3 coins. You have used a total of 9 coins, with the stack of 3 coins doing double duty for both rows.
You can use 3 quarters 6 nickles and 5 pennies. 75 plus 30 equals 1 dollar and 5 cents plus 5 pennies is $1.10 3 plus 6 is 9 plus 5 equals 14. So now you know you have 14 coins and $1.10
