| After |
1x3 =

2x3 =
6 u |

The amount of savings that Nicole has at first and in the end remains unchanged. Make the amount of savings that Nicole has the same. LCM of 3 and 1 is 3.
Amount that Henry saved
= 6 u - 1 u
= 5 u
5 u = 100
1 u = 100 ÷ 5 = 20
Total savings at first
= 3 u + 1 u
= 4 u
= 4 x 20
= $80
Answer(s): $80
