conversations.value: Find the answer to the math problem: On a mall-wide sale, Andre bought a $1350 treadmill for a 30% discount and 2 pieces of 45-pound plates for $50 each. How much did Andre pay for the treadmill and plates?
conversations.from: assistant
conversations.value: Andre had $1350 x 30/100 = $405 discount for the treadmill.
  So, a treadmill cost $1350 - $405 = $945.
  Two 45-pound plates cost $50 x 2 = $100.
  So, Andre paid a total of $945 + $100 = $1045.
