​Find the amount of interest Diego earned after four years.

1 answer

To calculate the simple interest earned by Diego, you can use the formula for simple interest:

I=P×r×t

where:

  • I is the interest,
  • P is the principal amount (initial deposit),
  • r is the rate of interest (expressed as a decimal),
  • t is the time in years.

In this case:

  • P=10,000
  • r=6
  • t=4 years

Now, we can calculate the interest:

I=10,000×0.06×4 I=10,000×0.24 I=2,400

So, the interest earned after four years is $2,400.

To find the total amount Diego will have after closing his account, we add the interest to the principal:

Total Amount=P+I=10,000+2,400=12,400

Therefore, Diego will have a total of $12,400 after four years.
