if your 8 dollar gets up by %5 every day how much money would you have after 40 days

To calculate how much money you would have after 40 days if your $8 increases by 5% every day, we can use the formula for compound interest:

\[
A = P \times \left(1 + \frac{r}{100}\right)^n
\]

Where:
- $ A $ is the amount of money after $ n $ days.
- $ P $ is the initial amount ($8 in this case).
- $ r $ is the daily percentage increase (5% in this case).
- $ n $ is the number of days (40 days in this case).

Substituting the given values:

\[
A = 8 \times \left(1 + \frac{5}{100}\right)^{40}
\]

Let's calculate it.

\[
A = 8 \times \left(1.05\right)^{40}
\]

Now, solving for $ A $:

\[
A \approx 8 \times 7.04 \approx 56.32
\]

After 40 days, you would have approximately **$56.32**.
