At First:
1 out of 4 units of Daisy = 1 out of 5 units of Christine
Daisy had 4 units and Christine had 5 units
Change:
Daisy spent $300 (4 units less $300)
Christine had $80 more (5 units plus $80)
At the End:
Christine had 3 times as much as Daisy had left.
If Daisy had 3 times of what she had at first (12 units) and spent 3 times of $300 ($900), she would have the same amount left as Christine. Illustrated in the 3rd bar model and compared to Christine's bar model.
