Final answer:

The compound amount after 19 years for an $11,000 deposit at 2% compounded monthly is approximately $15,603.06, calculated using the compound interest formula. This amount is not one of the provided choices, but the closest match is $15,541.28.

Step-by-step explanation:

To find the compound amount after 19 years for a $11,000 deposit at 2% compounded monthly, we use the formula for compound interest: A = P(1 + r/n)nt.

Where:

  • A is the amount of money accumulated after n years, including interest.
  • P is the principal amount (the initial amount of money).
  • r is the annual interest rate (decimal).
  • n is the number of times that interest is compounded per year.
  • t is the time the money is invested for, in years.

Substituting the given values:

P = $11,000
r = 0.02 (2% as a decimal)
n = 12 (compounded monthly)
t = 19

The formula becomes: A = 11000(1 + 0.02/12)(12)(19)

Calculating the compound amount:

A = 11000(1 + 0.00166667)228
A = 11000(1.00166667)228
A = 11000(1.41846)
A = $15,603.06

The compound amount after 19 years is approximately $15,603.06, which is not an exact match to the provided options. However, the closest answer among the choices is $15,541.28, which might indicate a slight difference due to rounding at different steps in the calculation process.
