What is in this set

The numbers in this set run from 5 to 600.
Every problem in it will go down.
A careful solution takes 2 written steps on average.
The mistake this set invites most often, in 100% of the problems: that is the amount taken off, not the new price — it still has to be taken from 120.
Answers are a decimal.

Drawing 240 problems from this page produced 149 different ones, 62% — so a sheet of 20 is a new sheet almost every time.

The same skill, harder or easier

We would put this in front of a grade 7 class. That is our judgement, not a standard, and it is printed here so you can disagree with it. Everything else we put in that year.
