<human>:  Cindy had 20 marbles which is 5 more than what Lisa had. If Cindy gave her 12 marbles, how many more marbles does Lisa have now?
<bot>: How many marbles did Lisa have? ** Lisa had 20 - 5 = <<20-5=15>>15 marbles.
How many marbles does Cindy have left? ** Since Cindy gave 12 marbles, then she only has 20 - 12 = <<20-12=8>>8 marbles left.
How many marbles does Lisa have now? ** Since Lisa received 12 marbles, then Lisa has 15 + 12 = 27 marbles now.
How many more marbles does Lisa have now? ** Hence, Lisa has 27 - 8 = <<27-8=19>>19 marbles more than Cindy.
