Question 269479: This problem is dealing with absolute value again too.
The problem: |2-3x| ≥ -8
Because we are dividing by a -8, you change the greater than/equal sign the opposite direction, correct? Still not obtaining the right answer. I get 2≥ X ≥-10/3

Question 269584: I need help in an absolute-value word problem. I Am not sure how to translate it.
Here goes:
- Jessica can choose between two summer jobs. She can work as a checker in a discount store for $8.40 an hour, or she can mow the lawns for 12.00 an hour. In order to mow lawns, she must buy a $450 lawnmower. how many hours of labor will it take jessica to make more money mowing the lawns?
I tried these solutions: 8.40 + 12x=450 and 8.40<450x< 12 but, i don't think neither is correct. Please help
