Question

A furniture maker uses the specification 21.88 (<=) w (<=)22.12 for the width w in inches of a desk drawer. Write the specification as an absolute value inequality.
A) |w- 0.24|(<=) 22.12
B) |w- 22 |(<=) 0.24
C) |w- 0.12| (<=) 22
D) |w- 22| (<=) 0.12

Answer 1

Data: 

21.88 (<=) w (<=) 22.12
w (<=) 22.12 - 21.88
w (<=) 0.24

Therefore, we have:
Iw - 0.24 I (<=) 22.12


Answer
A. Iw - 0.24I (<=)  22.12
