calling all word problem lovers! Sam has $0.93 in a total of nine coins. She does not have a half dollar. How many of each coin does she have? Pennies, nickels, dimes, quarters

    keep in mind that we can use two quarters or five dimes because Sam does NOT have $0.50

    She must have 3 pennies since there is no other way to represent $.01. This leaves 6 coins to make $.90. If we use two quarters as well, we have accounted for $.53, which leaves us with $.40 to account for. For this we can use four times. Her coins are 3 pennies, 4 dimes, and 2 quarters. 3 + 4 + 2 = 9 coins .03 + .40 + .50 = .93

    A half dollar is another kind of coin. Are you sure the problem is just not ruling out that sort of coin as an option?

    Mmhm. Don't see them a lot these days, though. I'm not sure of any other way to come up with her coinage.

    We don't need to use any nickels. We would have to use at least ten coins for that (3 pennies, 2 nickels, 3 dimes, 2 quarters, because 2 nickels replaces one dime).
