| Before |
2x2 =
4 u |
4x1 =
4 u |
| Change |
- 1x2 =
- 2 u |
- 3x1 =
- 3 u |
| After |
1x2 =
2 u |
1x1 =
1 u |
The amount that Albert and Zara had at first is the same. Make the amount that Albert and Zara had at first the same. LCM of 2 and 4 is 4.
Amount that Zara spent more than Albert
= 3 u - 2 u
= 1 u
1 u = 18
Amount that Albert had at first
= 4 u
= 4 x 18
= $72
Answer(s): $72
