Comparing between
Warren and Will
in the end |
4x2 =
8 u |
1x2 =
2 u |
$330 |
The amount that Will had in the end is the repeated. Make the amount that Will had in the end the same. LCM of 2 and 1 is 2.
10 u = 330
1 u = 330 ÷ 10 = 33
5 u = 5 x 33 = 165
3 p = 330 - 165 = 165
1 p = 165 ÷ 3 = 55
Amount that Warren had at first
= 5 p
= 5 x 55
= $275
Amount that Will had at first
= 330 - 275
= $55
Answer(s): $55
