A bell curve describes a random distribution where at either end is a low amount with the middle representing a higher amount of points.
So at either ends are “extremes” were someone scored really low or really high. The middle presents the average where most people will score
X-13=42
x is the "variable", you're taking 13 away from that, and the answer is also given, 42.
<span>you could have 3.15=100 times 0.0315, 10 times 0.315.</span>
Let the common multiple be x
3x : 2x
3x = 125
x = 125/3
So, B pays 2x = 2 × 125/3 = £250/3
