Your specific question was how many " hours " did he work this week so,

Monday: 7 whole hours
Tuesday: 5 whole hours
Wednesday: 6 whole hours
Thurs.-Fri.: Was off.

So that makes 7+5+6=18 hours.

The 30 minutes from Monday & 20 minutes from Tuesday doesn't equal one whole hour so it doesn't count.

Mrrafil [7]
Answer : D

WORK...
|3x-3| \leq 18


PART 1:
3x-3 \leq 18
 add 3 on both sides... 3x \leq 21 divide by 3 on both sides... x \leq 7

PART 2:
3x-3 \geq -18  add 3 on both sides... 3x \geq -15
 divide 3 on both sides... x \geq -5

plug both answers together..
-5 \leq x \leq 7
