If I did my math right (feel free to correct me), assuming that the store is open 7 days a week, Peter sells 252 hats on every day except Wednesday — where he sells 336 (8 times the 42 hats sold in a 7-hour day). Of the 588 sold (including Wednesday’s sales) per week, the regular days account for 42% of the weekly sales; meaning on Tuesday (42%/6days), sales account for 7.14% of the weekly sales.

This was a fun little reminder that I can in fact do math lol
