Hi forum experts,
I stumbled yet another P4 parts and whole question. Even though I have the answer I can't figure out why the model is drawn that way.
Connie and Alice had an equal amount of money.
Connie gave Alice $126.
Alice then had 4 times as much money as Connie.
How much money did Connie have at first?
I don't quite get it when the model shows Connie has two units and Alice got two units (after they draw the 1 : 4). :(
Hope someone can kindly enlighten me.
Thank you very much.

Hi,
Hopefully can solve your problem.
Try to attach the file but unsuccessful
252 / 3 = 84
1 block is 84
Corrine = 84+126 = 210
Alice = (84*4)126 = 336126 = 210

Hi, sorry I do not know how to draw model here, please refer to the attachment.
[file]
After giving away $126 to Alice, Connie is left with 1 unit.
Alice would have 4 units which were 1 unit + $126 + $126
3 units = $252
1 unit = $252 / 3 = $84
Now Connie has $84
She had $84 + $126 = $210 at first.

My heartfelt thanks to both of you.
Actually, I was racking my head why 3 units equal $252 because I kept thinking it should be 4 parts against 1 part.
Then, I asked my friend and realised that 4 units  1 unit = 3 units. And hence the initial equal of Alice vs Connie is 2 units vs 2 units.
Hope my understanding is correct. Do correct me if I'm wrong.
Once again THANKS for taking the effort to explain to me.
