The effective annual interest rate is:
i = (1 + 0.064/12)^12 - 1 = 0.066
In year 1: the interest is $613.80 (multiple $9300 by 0.066)
In year 2: the interest is $654.31 (add interest from year 1 to $9300 and multiply by 0.066)
In year 3: the interest is $656.98 (do the same as year 2)
In year 4: the interest is $657.16

The total interest is: $2582.25
The present worth of this amount is:
P = 2582.23 / (1 + 0.066)^4 = $1999.72

The answer is $1999.72.

Evaluate the following (1.6 x 10 12) ÷ (8.01 x 10 23)

devlian [24]

To evaluate the given expression, we must follow the rules of PEMDAS (Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction) in solving.

Therefore, first calculate what's inside the parentheses:

(1619.2) / (8194.23)

Then perform the operation in between the parentheses:

(1619.2) / (8194.23) = 0.20

Therefore the answer after evaluating the expression is 0.20.

I hope my answer has come to your help. Thank you for posting your question here in Brainly.
