Samarium-145 is a radioactive isotope of the element samarium with a half-life of approximately one year. So if you started with an ore sample with 15 grams of samarium-145, after one year there would only be 7.5 grams of samarium-145 left. (The rest would have converted to an isotope of promethium.)

For a sample that started with 15 grams of samarium-145, write an equation for calculating the remaining amount (y) after a certain number of years (x)
y=

Based on this pattern, how much samarium-145 would be left in the sample after 10 years?
