Answer:
16 cents, 32 cents, 48 cents, 64 cents, 80 cents, or 96 cents
Step-by-step explanation:
Well considering that there will always be a 1:1:1 ratio, we can just start by adding up each amount of coin
If we had 1 penny, 1 nickel, and 1 dime, that would give us 16 cents
If we had 2 pennies, 2 nickels and 2 dimes, that would give us 32 cents
3 pennies, 3 nickles, and 3 dimes for 48
4 pennies, 4 nickels, and 4 dimes for 64
5 Pennies, 5 Nickels and 5 Dimes for 80
6 Pennies, 6 Nickels, and 6 Dimes for 96
Any more would put us about that 1 dollar limit, so he could potentially have 16 cents, 32 cents, 48 cents, 64 cents, 80 cents, or 96 cents
