Final answer:

The amount in the account at the end of 1 year would be $4770, and at the end of 2 years would be $5058.20, based on a 6% interest rate compounded annually from an initial deposit of $4500.

Step-by-step explanation:

The student's question pertains to the calculation of compound interest for an initial deposit made in a bank account.

(a) To find the amount in the account at the end of 1 year, we use the formula for compound interest:

A = P(1 + r/n)^(n*t)

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 (in decimal).
  • n is the number of times that interest is compounded per year.
  • t is the time the money is invested for in years.

Given that P = $4500, r = 0.06 (since 6% = 0.06), n = 1 (compounded once a year), and t = 1, we find that:

A = 4500(1 + 0.06/1)^(1*1)

A = 4500(1 + 0.06)

A = 4500(1.06)

A = $4770 at the end of 1 year.

(b) To find the amount in the account at the end of 2 years:

A = 4500(1 + 0.06/1)^(1*2)

A = 4500(1 + 0.06)^2

A = 4500(1.06)^2

A = $5058.20 at the end of 2 years.
