 <translate> The cost of the pots is 3 * $20 = $60. The cost of 4 pans is $100 - $60 = $40. Since each pan is the same price, the cost of 1 pan is $40 / 4 = $10. The cost of 2 pans is $10 + $10 = $20.
Thus, the answer is 20. <yor> Iye tí àwọn ìkòkò náà ń ná ni 3 * $20 = $60. Owó tí wọ́n máa ń san fún páànù mẹ́rin jẹ́ $100 - $60 = $40.
