In Exercises 31 through 38, write a program to answer the question.

Radioactive Decay Strontium-90, a radioactive element that is part of the fallout from nuclear explosions, has a half-life of 28 years. This means that a given quantity of strontium-90 will emit radioactive particles and decay to one-half its size every 28 years. How many years are required for 100 grams of strontium-90 to decay to less than 1 gram? See Fig. 6.13.
