Answer:
Written in Python:
dollars = int(input("Amount: "))
numFive = int(dollars/5)
numOnes = dollars%5
print(str(dollars)+" yields "+str(numFive)+" fives and "+str(numOnes)+" ones.")
Explanation:
This line prompts user for input
dollars = int(input("Amount: "))
This line calculates the number of 5 that can be gotten from the input. This is done using integer division
numFive = int(dollars/5)
This line gets the remaining ones. This is done by using the modulo sign to get the remainder when input is divided by 5
numOnes = dollars%5
This line prints the required output
print(str(dollars)+" yields "+str(numFive)+" fives and "+str(numOnes)+" ones.")
