Question
Pennies for Pay
Write a program that calculates the amount of money a person would earn over a period of time if his or her salary is one penny the first day, two pennies the second day, and continues to double each day. The program should ask the user for the number of days. Display a table showing what the salary was for each day, and then show the total pay at the end of the period. The output should be displayed in a dollar amount, not the number of pennies.
Answer
Pennies for Pay program code:
#Prompt and read the number of days
numDays = int(input("Enter the number of days: "))
#Initialized variables
totalPay = 0
salary = 0.01
#Display a table showing what the salary was for
#each day, and then show the total pay at the end
#of the period. The output should be displayed
#in a dollar amount, not the number of pennies
print("Day\tSalary")
print("----------------")
for day in range(1, numDays + 1):
totalPay += salary
print(f"{day}\t${salary:.2f}")
salary *= 2
totalPay = "${:,.2f}".format(totalPay)
print("\nTotal pay: ", totalPay)
Executed Output:
Enter the number of days: 20
