Half-life of a radioactive substance is 2.9 days and the amount of substance is 10 mg. How many micrograms of the substance will be left after 29 days.

Explanation

To solve the problem step by step, we will use the concept of half-life of a radioactive substance. The half-life is the time required for a quantity to reduce to half its initial value.

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Half-life (T₁/₂) = 2.9 days
- Initial amount of substance (N₀) = 10 mg
- Total time (t) = 29 days
