Automobiles!
 
:question::smile:

This is an easy one but holds an important principle to see through.

Question: An automobile agency found that their total annual receipts for the sale of automobiles came to $ 1,111,111.00 but somewhere they lost the record indicating how many cars they had sold. Can you help them? :question:

Are we supposed to assume that 1 car for $1,111,111.00
or 1111111 for $1.00
are not reasonable solutions?

And that fractions of a dollar are not allowed?

Otherwise, factor 1111111 and use one factor for the price
and the other for the number.

Assuming this is correct, the answer is [spoiler]239 cars at $4649 each or 4649 cars at $239 each. Both have rather low car costs, but I'd say it's the first one. So the answer is 239 cars at $4649.[/spoiler]

Mally :coffee:[/QUOTE]No, I can't help them. Every automobile agency (or car dealerships as we call them) I've ever come across sell a number of different models at a variety of prices.

Your problem is under determined.

:wink: Well probably it was the 'Folks' wagon or a Russian agency selling only Zim cars. For that matter selling jeeps at war time by the U.S. for the army. They eventually filtered down to the Indian army. :grin: That explains the low price.

:tu: I accept your answer Mini Geek as the best of the lot.
Davar's is okay but he left out the factors.
