He also increased the price of each painting by 20 / 100 * 100 = $20. The total price for buying one painting at the new price is $100 + $20 = $120. If a buyer purchases two pieces of jewelry, the total cost becomes 2 * $40 = $80. When the buyer also buys 5 paintings, he pays a total of $120 * 5 = $600. 2 pieces of jewelry and 5 paintings cost $600 + $80 = $680 at the new prices.
Thus, the answer is 680.
