Question

Write a python program for the following problem?

100. Cost of Electricity formula The cost of the electricity used by a device is given by the cost of electricity (in dollars) = wattage of device. hours used 1,000 · cost per kWh (in cents) where kWh is an abbreviation for "kilowatt hour.” The cost per kWh of electricity varies with locality. Suppose the current average cost of electricity for a residential customer in the United States is 11.76¢ per kWh. Write a program that allows the user to calculate the cost of operating an electrical device. Figure 2.10 calculates the cost of keeping a light bulb turned on for an entire month. Enter wattage: 100 Enter number of hours used: 720 Enter price per kWh in cents: 11.76 Cost of electricity: $6.12

Answer 1

Screenshot of the code:

#Prompt the user to enter the wattage, #hours and price in cents. wattage = int(input("Enter wattage: ")) hours = int(input ("Enter number of hours used: ")) price = float (input ("Enter price per kWh in cents: ")) #Compute the cost of electricity. Cost = (wattage * hours)/(1000 * price); #Display the output, Cost of electricity. print("Cost of electricity: $"+"{: .2f}". format (Cost));

Sample Output:

Enter wattage: 100 Enter number of hours used: 720 Enter price per kWh in cents: 11.76 Cost of electricity: $6.12

Code To Copy:

#Run the code in python version 3.x.

#Indent the code as per the above screenshot of the code.

#Prompt the user to enter the wattage,
#hours and price in cents.
wattage = int(input("Enter wattage: "))
hours = int(input("Enter number of hours used: "))
price = float(input("Enter price per kWh in cents: "))

#Compute the cost of electricity.
Cost = (wattage * hours)/(1000 * price);

#Display the output, Cost of electricity.
print("Cost of electricity: $"+"{:.2f}".format(Cost));
