Answer 2

Answer:

Amount of money in the account:   $2,269.25

Interest: $269.25

Step-by-step explanation:

John starts out with $2000 in savings.

(I can't be bothered to find the formula for annual compound interest, so we'll do it manually based on yearly calculations.)

Because it is calculated annually, we must do yearly calculations.

Year One:

2,000 x 1.043 = 2,086.00

After the first year, at 4.3% John's $2000 Savings account would mature into $2,086.00. (earning him $86.00 interest for the year)

Year Two:

2,086.00 x 1.043 = 2,175.70

After, the second year at 4.3%,  $2,086.00 becomes $2,175.70.  (making his interest $175.70 total, and $89.70 for the year.)

Year Three:

2,175.70 x 1.043 = 2,269.25

After the third, and final year, at 4.3%, $2,175.70 becomes $2,269.25. (making the interest $269.25 or $93.56 for the year.)
