945.168 and round to nearest cent. is 950?

Your arithmetic is correct. Your rounding is wrong.

945.168 is nine hundred, forty-five, and 168 thousandths.

945.168 rounds to $945.17.

To find the simple interest, we use the formula:

Simple Interest = Principal * Rate * Time

Where:
Principal = $8439 (initial deposit)
Rate = 8% (interest rate)
Time = 1.4 years (length of time)

First, we convert the interest rate from a percentage to a decimal by dividing it by 100.

8% = 8/100 = 0.08

Now, we can calculate the simple interest:

Simple Interest = $8439 * 0.08 * 1.4

Next, we calculate the final value of the deposit by adding the simple interest to the initial deposit:

Final Value = Principal + Simple Interest

Final Value = $8439 + Simple Interest

Now, let's perform the calculations:

Simple Interest = $8439 * 0.08 * 1.4 = $939.24

Final Value = $8439 + $939.24

Final Value ≈ $9378.24

Therefore, the simple interest is approximately $939.24 and the final value of the deposit, rounded to the nearest cent, is approximately $9378.24.
