| Change |
- 1x3 =
- 3 u |
- 5x5 =
- 25 u |
|
| After |
5x3 =
15 u |
1x5 =
5 u |
|
Comparing Harry
and Cole in the end |
3x5 =
15 u |
1x5 =
5 u |
|
The amount that Harry had in the end is repeated. Make the amount that Harry had in the end the same. LCM of 5 and 3 is 15.
Total amount that Harry and Cole had at first
= 18 u + 30 u
= 48 u
48 u = 1776
1 u = 1776 ÷ 48 = 37
Amount that Cole had at first
= 30 u
= 30 x 37
= $1110
Answer(s): $1110
