4x1 =
4 u |
| Change |
- 3x2 =
- 6 u |
- 3x1 =
- 3 u |
| After |
2x2 =
4 u |
1x1 =
1 u |
Comparing Tammy
and Yoko in the end |
4x1 =
4 u |
1x1 =

The amount that Tammy had in the end is repeated. Make the amount that Tammy had in the end the same. LCM of 4 and 2 is 4.
Amount that Tammy had more than Yoko
= 10 u - 4 u
= 6 u
6 u = 240
1 u = 240 ÷ 6 = 40
Amount that Yoko had at first
= 4 u
= 4 x 40
= $160
Answer(s): $160
