A. 1000 watts is 1 kilowatt

Half of a kilowatt is 500 watts, or 0.5 of a kilowatt. 0.5 * 5 = 2.5

Or 500 watts * 5 hours (amount of time passing) = 2500

2500/1000 (or one kilowatt) = 2.5

2.5 kwh is the correct option

In summary, 1 kilowatt is 1000 watts

500 watts is half of a kilowatt

Every hour the appliance uses 500 watts or 0.5 (half) of a kilowatt

print("welcome to the bill calculator")

minutes = float(input("number of minutes you used: "))

data = float(input("the amount of data you used in GB: "))

print("your basic plan costs $39.99 per month")

mcost = (minutes - 450) * .45

print("you will be charged " +  str(mcost) + " for the minutes you used")

print("the monthly data fee is $30.00")

dcost = (data - 3) * 10

print("you will be charged " + str(dcost) + " for the extra data you used")

total = mcost + dcost + 69.99

print("your total bill is " + str(total))

the 20 value your teacher gave may be incorrect, bc 4.2-3*10 = 12 not 20, making the total 109.89

I'm guessing you mean the six external parts as in input and output devices

Here are the six external parts:

>Keyboard

>Mouse

>Monitor

>Speakers

>Printer

>Microphone or USB...I think you can choose either one as they are components outside of the computer/external/ -I/O devices
