Question

ROLLERCOASTER At a theme park, a person must be a certain height to ride a rollercoaster. A

Answer 1

Using absolute value, it is found that the correct option is:

Both Anoki and David are correct. Both expressions are equivalent to the difference  between the measurements and are always positive because they give the absolute  value of the difference.

-------------------------------------

The absolute value measures the distance between a point x and the origin, and thus:

$|x| = |-x| = x$

-------------------------------------

• The height is h, with an allowance of 1.5.
• Anoki says that one allowed height is |1.5 - h|. Since |1.5 - h| = |h - 1.5| = h - 1.5, it gives a height 1.5 less than h, which is allowed, thus, Anoki is correct.
• David gives an expression of h - 1.5, which is a modification of Anoki expression, also correct.
• Thus, the correct option is:

Both Anoki and David are correct. Both expressions are equivalent to the difference  between the measurements and are always positive because they give the absolute  value of the difference.
