# The mass of a radioactive substance decreases exponentially at a rate of 3% each day.(i) Find the overall percentage decrease at the end of 10 days

## Question

## Solution 1

To solve this problem, we need to understand that the decrease is not linear, but exponential. This means that each day, the substance decreases by 3% of its current mass, not its original mass.

Here are the steps to solve this problem:
