The formula for calculating simple interest is:
Interest = Principal * Rate * Time

Plugging in the given values:
Principal = $15,000
Rate = 4.8% = 0.048
Time = 30 years

Interest = $15,000 * 0.048 * 30 = $21,600

To find the final amount, we need to add the interest to the principal:
Final amount = Principal + Interest = $15,000 + $21,600 = $36,600

Therefore, the final amount of Chris's investment is $36,600.

I apologize for the mistake.
To find the final amount of Chris's investment, we can use the formula for compound interest:

Final amount = Principal * (1 + Rate)^Time

Plugging in the given values:
Principal = $15,000
Rate = 4.8% = 0.048
Time = 30 years

Final amount = $15,000 * (1 + 0.048)^30
Final amount ≈ $15,000 * (1.048)^30

Using a calculator, we find that (1.048)^30 ≈ 2.8969.

Final amount ≈ $15,000 * 2.8969
Final amount ≈ $43,403.50

Therefore, the final amount of Chris's investment is approximately $43,403.50.
