Hi
I do not understood, I happened to do this question but somehow Dun know,
How to do backwards and why the 4u is from?
The amount Peili had left was $7 more than what she had spent.
Spent ------ 2 units
Left ------- 2 units + 7
In the beginning (spent + left)------ 2 units + 2 units + 7
Nurul spent twice as much as Peili
Peili spent 2 units
Hence, Nurul ------ 4 units

HiHelp with this question,
(1)Mr Lee baked 185 more chicken pies than tuna pies. After selling 3/5 of the chicken pies and half of the tuna pies, he had 146 pies left. How many pies did he sell?
A neat way is to use MD. You may also use units.
At first
chicken pies ----- 10 units + 185
tuna pies ------ 10 units
sold
chicken pies ----- 6 units + 111
tuna pies ------ 5 units
In the end
chicken pies ----- 4 units + 74
tuna pies ------ 5 units
9 units + 74 ------ 146
1 unit ------ 8
Number of pies sold ------- 11 units + 111 ------- 88 + 111 ------ 199
