For this chain-of-thought reasoning and answer, what was the question?
2 / 5 of the total amount of sales Mr. Brandon made yesterday, which were credit purchases, were worth 2 / 5 * $80 = $32. The cash sales that Mr. Brandon made yesterday was $80 - $32 = $48.
 A: 48
Q: The buyers who came to Mr. Brandon's shop yesterday bought goods worth $80. If 2/5 of the total amount of sales Mr. Brandon made yesterday were credit sales, and the rest were cash sales, how much did Mr. Brandon get from cash sales?
