Answer: Option (B) is correct.
<em>Given:</em>
<em>P = $6000</em>
<em>r = 6%</em>
<em>t = 6 years and 7 months = 79 months</em>
∵ It is compounded semi-annually
∴ 

I = 8854.72 - 6000
<em>I = 2854.72</em>

<u>Proportions and Fractions
</u>
A proportion is expressed as a fraction a/b, where a and b are compared by division. If a=b, the proportion (or ratio) equals 1, if a<b, the ratio is less than 1, and if a>b, the ratio is greater than 1. The proportion of elements of a set to the total number of elements of the set is less than one, and the sum of all them equals 1.
We know 3/8 of Carl's rock collection are quartz and 1/3 are granite. If both subsets of rocks are mutually exclusive or disjoint (cannot happen simultaneously), then the proportion of both is the sum of the fractions.
