Nancy and a group of her friends took a bus trip.
Each person paid the bus driver with the same combination of 9 coins.
If the bus driver received $8.41 from the group, how many dimes did he receive?
Solution to the Problem:
Here is the solution:Since 841 = 292 and since 29 is a prime number, that means Nancy and her 28 friends could only have paid $8.41 in equal amounts by spending 29 cents each.
The only combination of 9 coins that yields 29 cents is 4 pennies and 5 nickels.
Therefore, the bus driver did not receive any dimes.
