Final answer:

The value of the investment after 1 year is approximately $820.16.

Step-by-step explanation:

To calculate the value of the investment after 1 year, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

A = the final amount (the value of the investment after 1 year)

P = the principal amount (the initial investment)

r = the annual interest rate (as a decimal)

n = the number of times that interest is compounded per year

t = the number of years

In this case, P = $800, r = 2.4% = 0.024 (as a decimal), n = 4 (quarterly compounding), and t = 1 year. We can plug in these values into the formula:

A = 800(1 + 0.024/4)^(4*1)

Simplifying the equation, we get:

A = 800(1.006)^4

Using a calculator, we can find that A is approximately $820.16.
