7x2 =
14 u |
4x3 =
12 u |
| Change |
- 4x2 =
- 8 u |
- 3x3 =
- 9 u |
| After |
3x2 =
6 u |
1x3 =
3 u |
Comparing Vanessa
and Tammy in the end |
2x3 =
6 u |
1x3 =
3 u |
The amount that Vanessa had in the end is repeated. Make the amount that Vanessa had in the end the same. LCM of 2 and 3 is 6.
Amount that Tammy had less than Vanessa
= 14 u - 12 u
= 2 u
2 u = 44
1 u = 44 ÷ 2 = 22
Amount that Vanessa had at first
= 14 u
= 14 x 22
= $308
Answer(s): $308
