assistant
How many apples are in the 4 bags? ** 4 bags have 4 x 20 = <<4*20=80>>80 apples.
How many apples are in the 6 bags? ** And, six bags have 6 x 25 = <<6*25=150>>150 apples.
How many apples does Ella have? ** Thus, Ella has 80 + 150 = <<80+150=230>>230 apples in all.
How many apples does Ella have left? ** Therefore, Ella has 230 - 200 = <<230-200=30>>30 apple left.
