At first,
Daisy --> 1 unit + $14
John --> 3 units + $42 (= 3 x $14)
In the end,
Daisy --> 1 unit
John --> 5 units
For John, 5 units --> 3 units + $ 42 + $14
1 unit --> $28
Daisy had $ 28 in the end.

Hi
I will use unit method here, but you can simply convert it into MD.
At first,
Blue : Yellow
--> 2 x (1u + 33) : 1u + 33
--> 2u + 66 : 1u + 33
In the end,
Blue : Yellow --> 1:3
--> 2u : 1u + 25
--> 2u : 6u
So, 5u --> 25, 1u --> 5
At first,
Blue : Yellow --> 76 : 38 -- total 114 clips.

HTH..
Before:
Blue clips ----- 2units
Yellow clips ----- 1unit
After:
Blue clips ----- 1 part ( 2u-66)
Yellow clips ----- 3 parts (1u-8)
1 part ------ 2u-66
So 3 parts ----- 6u-198
6u-198 = 1u-8
5u = 190
1u = 38
There were 3 units of clips at first
3u ----- 3 x 38 = 114 clips -
