Stan bought several clothing items at macys. He bought a jacket for $30.00, a hat for $10.00, and two shirts for $5.00 each. He had a coupon that took 30% off the total bill. He paid with a $50.00 bill and received three of the same types of bills in change. What were those bills ?

30 + 10 + 10 = 50
50 * 0.7 = 35
50  35 = ?
