C: OR Third Option
Antonio can avoid traffic if he works for LESS THAN 7 HOURS or GREATER THAN 9 HOURS.
Is there any COMMON point in those 2 statements? Is there any number that satisfy BOTH LESS THAN 7 and GREATER THAN 9?
No! So inequality can't be written as one, rather as 2 statements with an "or" in between.
So we can write LESS THAN 7 as , and
GREATER THAN 9 as
Hence, third choice is correct:
do you have the measurements?
