Simon and Cole had $580 altogether. After Simon spent
14 of his money and Cole spent
34 of his money, Simon was left with twice as much money as Cole. How much money did Cole have at first?

4x2 =
8 u |
4x3 =
12 u |
$580 |
| Change |
- 1x2 =
- 2 u |
- 3x3 =
- 9 u |
|
| After |
3x2 =
6 u |
1x3 =
3 u |
|
Comparing Simon
and Cole in the end |
2x3 =
6 u |
1x3 =
3 u |
|
The amount that Simon had in the end is repeated. Make the amount that Simon had in the end the same. LCM of 3 and 2 is 6.
Total amount that Simon and Cole had at first
= 8 u + 12 u
= 20 u
20 u = 580
1 u = 580 ÷ 20 = 29
Amount that Cole had at first
= 12 u
= 12 x 29
= $348
Answer(s): $348
