<h2>$4,160.625</h2>
Step-by-step explanation:
<h3>principle (p) = $15,850</h3><h3>rate (r) = 3.75%</h3><h3>time (t) = 7 years</h3><h3>simple interest = (p × r × t) ÷ 100</h3><h3> = (15850 × 3.75 × 7) ÷ 100</h3><h3> = 416,062.5 ÷ 100</h3><h3> = 4,160.625</h3>

Since it is given that the triangle is a right angle, and one of the other angles is 30 degrees, then we know that this triangle is a 30, 60, 90 triangle. In a 30, 60, 90 triangle, the opposite side of the shortest angle is half of the hypotenuse (which is given as 6). So knowing this, the value of y would be D. 3.
