Mr. Rocky went to the market to sell his handmade crafts on a particular week. He was selling jewelry at $30 each and paintings at $100 each. However, he realized the income from the sales wasn't worth the labor and materials he had used, so he decided to increase the price of jewelry by $10 each and the cost of each painting by 20%. Calculate the total price a buyer who takes two pieces of jewelry and five paintings would pay Think carefully first, then make a decision:

After increasing the price of a piece of jewelry, the price increased from $30 to $30 + $10 = $40 each. 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. So, the answer is 680.
