To calculate how much you will get back in 4 years, given a promised return of 145%, we can use the following steps:

Step-by-step solution:

1. Initial investment: $30,000
2. Return on investment (ROI): 145% over 4 years

To find out how much you will receive, you can use this formula:

$\text{Total Return} = \text{Initial Investment} \times \left(1 + \frac{\text{ROI}}{100}\right)$

Substitute the values:

$\text{Total Return} = 30,000 \times \left(1 + \frac{145}{100}\right) = 30,000 \times 2.45 = 73,500$

Answer:

You will receive $73,500 after 4 years.
