Hybrid Car

[sandoda]

It is supposed to look like this but for some reason when I enter (total) my code just stops. Im not really sure what I am doing wrong. I know this is a big question to ask but all help is appreciated



The estimated miles driven per year: 15000

The estimated price of a gallon of gas during the 5 years of ownership: -4.53

I'm sorry, you must enter a value bigger than zero. Please try again. Please enter:

The estimated price of a gallon of gas during the 5 years of ownership: 4.53

The initial cost of a hybrid car: 28000

The efficiency of the hybrid car in miles per gallon: 46.5

The estimated resale value (a dollar amount) for a hybrid after 5 years: 16000

The initial cost of a non-hybrid car: 0

I'm sorry, you must enter a value bigger than zero. Please try again. Please enter:

The initial cost of a non-hybrid car: 24000

The efficiency of the non-hybrid car in miles per gallon: 28.5

The estimated resale value (a dollar amount) for a non-hybrid after 5 years: 12000

The user's buying criterion, either minimized gas consumption or total cost (enter Gas or Total): Total

For the Hybrid Car:

The total gallons of fuel consumed over 5 years: 1612.90

The total cost of owning the car for 5 years: 19306.45

For the NON-Hybrid Car:

The total gallons of fuel consumed over 5 years: 2631.58

The total cost of owning the car for 5 years: 23921.05

@sandoda

You're program worked fine for me. I used all the inputs you show in your question, and it was fine. So, I'm thinking that you entered "total", and NOT "Total", with a capital 'T'
