basic python math problem

Question

Peggy listed a real estate property for a commission rate of 5.0%. Peggy’s brokerage will get half of the commission and Peggy’s share will be half of that. The property sells when reduced by 20%. Write a program that prompts for the original price of the listing. Your program should output the reduced selling price and Peggy’s commission in currency format with the $ sign right up against the first digit and two decimal places. Also, display commas as appropriate for amounts over $1,000.

Im looking for the most simple way to program this in python 

 

this is what i have come up with so far 

import locale
origpr = input('what is the original price')# original full price
discopr = int(origpr * 0.80) #answer to the property sells when reduced by 20%
comish = int(discopr * 0.05)#newprice times .05
broker = int(comish *.5)#brokers half the comission
peggy = int(broker *.5) #peggys comish
print'the discounted price is $'+format(discopr,'.2f')#print the reduced
print'Peggys comission is $'+format(peggy,'.2f')#print the reduced

Hi Maximilian,

 

So do you have a book that teaches you Python? You can also do "google" searches to help locate sample code. I will get you started.

 

For example her is a snippet from a google search result:

 

'''Conversion of strings to int before addition'''

xString = input("Enter a number: ")
x = int(xString)
yString = input("Enter a second number: ")
y = int(yString)
print('The sum of ', x, ' and ', y, ' is ', x+y, '.', sep='')

 

That shows you how to capture the original price, converting to integer.

 

For your purposes let's say you captured in the variable: orig.

 

The original price is reduced by 20%. Another way to say that is 80% of the original is what the new price will be.

 

So, newprice = .8 * orig

 

Now calculate the commission:

 

commission = .05 * newprice

 

The brokerage gets 1/2 of the commission:

 

broker = .5 * commission

 

And Peggy gets 1/2 of that:

 

peggy = .5 * broker

 

As far as printing the output, you will be using a print statement for the reduced selling price and Peggy's commission. Perhaps you can print on one line (or two separate if you want). But you have to figure out how to format it with a $ sign and two decimal places. Let's have you research how to do that.
