Question 206380

Since the store sold 2,500 copies and 670 copies remain unsold, then the total amount of books they had for sale was 3,170 (2,500 + 670).


Since 2,500 copies out of 3,170 copies were sold, then the percent of the total copies sold is:

{{{2500/3170*100}}} = {{{25000/317}}} = {{{highlight_green(78.86)}}}%.
