When she put them in the sun to dry, 2/5*80 = <<2/5*80=32>>32 of the clay pots that Cheyenne made cracked and could not be sold.
The number of pots that were good for sale is 80-32 = <<80-32=48>>48
If she sold each clay pot at $40, she earned $40*48 = $<<40*48=1920>>1920 from selling the good pots.
