Question: Break down this math problem: Cheyenne is a craftswoman making pots for sale. On a particular week, she made 80 clay pots. However, when she put them in the sun to dry, 2/5 of the pots cracked and could not be sold. How much money did Cheyenne make from selling the remaining items at $40 per clay pot?
Answer: 
When she put them in the sun to dry, 2/5*80 = 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 = 48
If she sold each clay pot at $40, she earned $40*48 = $1920 from selling the good pots.
