Eastman Kodak could sell the brownie for very little because it knew it would make money on film and photo processing. What would be the best equivalent to this in today’s society.

A. Cars that require gas in maintenance
B. Inexpensive, printers, and costly ink cartridges.
C. Food services with additional cost for take out
D. Sports clothes that are making jackets and pants.

B. Inexpensive printers and costly ink cartridges.

The best equivalent to Eastman Kodak selling the Brownie camera for very little while making money on film and photo processing in today's society would be:

B. Inexpensive printers and costly ink cartridges.

Similar to how Kodak offered affordable cameras but profited from the sale of film and photo processing, some printer manufacturers today offer inexpensive printers but make their money by selling expensive ink cartridges.

The best equivalent to Eastman Kodak's business model in today's society would be B. Inexpensive printers and costly ink cartridges.

Just like Kodak sold the Brownie camera at a low price, knowing they would make profits from film sales and photo processing, printer manufacturers today often sell their printers at affordable prices, while the ink cartridges can be quite expensive. This strategy allows printer manufacturers to attract customers with the low initial investment, and then generate ongoing revenue from the sales of ink cartridges.

To get this answer, I analyzed the options and identified the one that closely resembles Kodak's business model in terms of selling cheap hardware and earning profits from consumables or complementary products.
