| Change |
- 1x3 =
- 3 u |
- 3x5 =
- 15 u |
|
| After |
5x3 =
15 u |
1x5 =
5 u |
|
Comparing Justin
and Wesley in the end |
3x5 =
15 u |
1x5 =
5 u |
|
The amount that Justin had in the end is repeated. Make the amount that Justin had in the end the same. LCM of 5 and 3 is 15.
Total amount that Justin and Wesley had at first
= 18 u + 20 u
= 38 u
38 u = 1140
1 u = 1140 ÷ 38 = 30
Amount that Wesley had at first
= 20 u
= 20 x 30
= $600
Answer(s): $600
