For 3a, we see that it states that the submarine is 800 feet below sea level. Since it is below sea level, it is negative (as sea level is 0) and therefore -800, making ii correct.

For 3b, since the elevation is -150 feet, and negative means below sea level, the reef is 150 feet below sea level, making i correct.

what was the interest rate if your balance on an investment of 857 dollars at the end of six years is 1268.36 dollars​
Mumz [18]
<h3>The interest rate is 8 % if your balance on an investment of 857 dollars at the end of six years is 1268.36 dollars​</h3>

<em><u>Solution:</u></em>

Given that,

Principal = $ 857

Amount = $ 1268.36

Number of years = 6

Rate of interest = ?

Simple Interest = Amount - principal

Simple Interest = 1268.36 - 857

Simple Interest = 411.36

<em><u>Use the formula,</u></em>

Simple Interest = \frac{ p \times n \times r}{100}\\\\411.36 = \frac{ 857 \times 6 \times r}{100}\\\\41136 = 5142 \times r\\\\r = \frac{41136}{5142}\\\\r = 8 \%

Thus the interest rate is 8 %
