List the Facts (Spit it Back)!

  • She paid $35

  • She saved more than 30% (which means she paid less than 70% of the original value)

  • Our inequality symbol should be < or > because a 30% savings is not part of the solution.  30% will be our "border"

  • if she had saved exactly 30%, the price of teh pocket book would have been 70% of the original price


let x = the original price

      35 < .70<< divide both sides by .70 >>

      50 < x  or        x > 50

The original price was more than $50!
