Question 1109244: https://imgur.com/a/H4UUq
The original statement was an OR statement, which lead me to conclude then that I inverted/negated ALL statements. Namely,
x>= -1 AND x<1
as opposed to
x<=-1 OR x>1
And that it was on that basis that I selected the final answer (which has been identified as being wrong). Where did I go wrong?
I then thought perhaps the answer was the 1st one by virtue of the fact that it also had an "and" statement contained within it, but I must confess to being baffled now. :(
Why do the 2nd and 3rd answers not include the word AND? Is there a significance?
I thought that to negate an equality sign, you merely flipped it. > becomes <, and <= becomes >=.
The correct answer was the 2nd answer, which my reading of it means that:
"x is less than -1 AND x is less than or equal to 1."
Going with my (flawed I assume) logic above of merely flipping the equality operators I thought this would have actually have been
x is less than or equal to -1 AND X is greater than 1"

Question 1109909: Clintonville Landscapers (CL) Charges a delivery fee of $30 regardless of the amount of mulch delivered within a 20mile radius. The cost of Absolute Black Ultra mulch is $39.99 per cubic yard at CL. Oregonia Nursery is having a special and charges $28.49 for the same mulch, but their delivery charge is $50 per transaction. For how many cubic yards is buying mulch from Oregonia Nursery cheaper? Round your answer to the nearest tenth.
So, that is the question. I know how to solve an inequality such as a flat rate + $ per mile (as an example) with only a certain dollar amount I'm able to spend. Not sure how to approach this one though.
