- 4x3 = - 12 u |
- 2x1 = - 2 u |
After |
1x3 = 3 u |
3x1 = 3 u |

25 Pamela and Shannon had the same amount of money in the end. Make the amount that each had in the end the same. LCM of 1 and 3 is 3.
Amount that Pamela had more than Shannon at first
= 15 u - 5 u
= 10 u
10 u = 160
1 u = 160 ÷ 10 = 16
Amount that Pamela had in the end
= 3 u
= 3 x 16
= $48
Answer(s): $48
