What is in this set

The numbers in this set run from 2 to 15.
Every problem in it will take two steps.
A careful solution takes 3 written steps on average.
The mistake this set invites most often, in 100% of the problems: that is the area in square feet; each of them costs more than a dollar.
Answers are an amount with two decimal places.

Drawing 240 problems from this page produced 220 different ones, 92% — so a sheet of 20 is a new sheet almost every time.
