∙ 10y agoEvery time one half-life passes, the amount of a substance is decreased by a factor 2. In other words, after one half-life, 1/2 of the original substance is left; after two half-lives, 1/4 of the original substance is left; after 3 half-lives, 1/8 of the original substance is left; etc.

Cylinders are 25 percent off. Mrs Delmar buy 4 8 each and 6 9.50 each. What percent of the original price will Mrs Delmar pay?

Many real world phenomena can be modeled by functions that describe how things decay as time passes. Examples of such phenomena include the studies of populations, bacteria, the AIDS virus, radioactive substances, electricity, temperatures and credit payments.Any quantity decays by a fixed percent at regular intervals is the exponential decay.
