A local college bookstore paid a net price of $12,500 for textbooks for the coming semester. The publisher offered a trade discount of 20%. The publisher's original list price was ______
The original price is 100%. A local college bookstore paid $12,500 which is 80% of the original price because he got 20% discount (100% - 20% = 80%).
Now, make a proportion. If $12,500 is 80% of the original price, how much $ is original price (100%): $12,500 : 80% = x : 100 % x = $12,500 · 100% ÷ 80% = $15,625
