Every Tuesday, Daniel delivers 20 x 2 = <<20*2=40>>40 yards of fabric.
Every Wednesday, he delivers 40 x 1/4 = <<40*1/4=10>>10 yards of fabric.
Thus, he delivers a total of 20 + 40 + 10 = <<20+40+10=70>>70 yards of fabric from Monday to Wednesday.
Therefore, Daniel earns $2 x 70 = $<<2*70=140>>140 from it.
