The first Earth Day was observed on April 22, 1970. Since then, the week of April 22 has been Earth Week, a time for showing support for environmental causes. Fans Cafe is offering a reduced refill rate for soft drinks during Earth Week for anyone purchasing a Fans mug. The mug costs $2.95 filled with 16 ounces of soft drink. The refill price is $0.50. A 16-ounce drink in a disposable cup costs $0.85.

What is the approximate break-even point for buying the mug and refills in comparison to buying soft drinks in disposable cups?
