$837 - $648 = $189
$189 x 3 = $570 - $3 = $567
$837 - $567 = $270
Sam had $270 at first.
Assuming Sam did not spend his money:
Edward had $360 at first.
Jason had $837 - $360 - $270 = $207 at first.
Jason had $207 at first.

5 units = 2470 + 3560 = 6030
1 unit = 6030 5 = 1206
4 units = 1206 x 4 = 4824
In the end …..
2 442, 24
The difference between 42 and 24 is
18.
