You need a split statement like C or D. A and B would have to be considered if the ages were between 12 and 60. However the discounts apply the other way. Up to 12 and over 60. You need two inequalities to describe this.
<em><u>Under 12</u></em>
x ≤ 12
The pointy end of the arrow points toward the x. x must be less than or at most equal to 12. The pointy end of the inequality must be directed towards the smaller number.
<em><u>Over 60</u></em>
x ≥ 60
This time the pointy end is directed towards the 60. x must be at least 60 and then upwards.
) we have let 'x' represent our original length.
So our original length is
