John has $100 in his pocket. He spends $25 each time he fills his car with gas. (John obviously doesn't drive my minivan.) How many fillups can John afford if he wants to keep at least a $10 emergency fund? Let x = # of fillups 100-25x >= 10 - 25x >= -90 x <= 3.6 If John needs more than 3 fillups, he kills his emergency fund. OK, maybe not my best work. But it's 7:25 am and I'm on vacation.

It looks as though you're teaching either Pre-Algebra or Algebra I, is that correct? What topics are coming up? Let me root through my files and see if there's anything you can use.

I was teaching Algebra I at the time I asked that question. Then I was teaching Algebra II then and some of the students had trouble with negative inequalities then too. Right now, I'm teaching Algebra II and AP Calc in a cyber environment. Sorry for not checking for so long. I hope all is going well for you, Aliceacc!
