jimmy has a bag that contains 50 coins. the total value of these coins is 1.00
can you tell how many quarters, dimes, nickels, and pennies are in the bag
If he had 1 quarter, 1 dime, and 1 nickel, that would be 40 cents, and he'd
need 60 pennies. That'd be 63 coins. Too many!
If he had 2 quarters, 1 dime, and 1 nickel, that would be 65 cents, and he'd
need 35 pennies. That'd be 39 coins. Too few!
So he can only have 1 quarter.
If he had 1 quarter, 2 dimes, and 1 nickel, that would be 45 cents, and he'd
need 55 pennies. That'd be 59 coins. Too many!
If he had 1 quarter, 3 dimes, and 1 nickel, that would be 60 cents, and he'd
need 40 pennies. That'd be 45 coins. Too few!
So he can only have 2 dimes.
If he had 1 quarter, 2 dimes, and 2 nickels, that would be 50 cents, and he'd
need 45 pennies. That'd be 50 coins. Hey! Cool! That's the answer!
