John had $200. He gave 3/8 of his money to his mother and 3/10 to his father. How much money did John have left?
John's mother received 3/8 x $200 = $<<3/8*200=75>>75.
His father got 3/10 x $200 = $<<3/10*200=60>>60.
Thus, John gave a total of $75 + $60 = $<<75+60=135>>135.
Therefore, John had $200 - $135 = $<<200-135=65>>65 left.
