print("Enter an amount in double: ")
amount = float(input())
remainingAmount = int(amount * 100)
#Find the number of one dollars
numberOfOneDollars = remainingAmount / 100
remainingAmount = remainingAmount % 100
#Find the number of quarters in the remaining amount
numberOfQuarters = remainingAmount / 25
remainingAmount = remainingAmount % 25
#Find the number of dimes in the remaining amount
numberOfDimes = remainingAmount / 10
remainingAmount = remainingAmount % 10
#Find the number of nickels in the remaining amount
numberOfNickels = remainingAmount / 5
remainingAmount = remainingAmount % 5
#Find the number of pennies in the remaining amount
numberOfPennies = remainingAmount
#Display results
print("Your amount {} consists of".format(amount))
if (numberOfOneDollars == 1):
print(" {} dollar ".format(numberOfOneDollars))
elif (numberOfOneDollars > 1):
print(" {} dollars".format(numberOfOneDollars))
if (numberOfQuarters == 1):
print(" {} quarter ".format(numberOfQuarters))
elif (numberOfQuarters > 1):
print(" {} quarters ".format(numberOfQuarters))
if (numberOfDimes == 1):
print(" {} dime ".format(numberOfDimes))
elif (numberOfDimes > 1):
print(" {} dimes ".format(numberOfDimes))
if (numberOfDimes == 1):
