Last month, Min had four times as much savings as Julian. This month, Julian saves $210. As a result, he now has twice as much savings as Min. What was their total savings at first?

4 u |
1 u |
5 u |

+ $210 |

After |
1x4 = 4 u |
2x4 = 8 u |
|
The amount of savings that Min has at first and in the end remains unchanged. Make the amount of savings that Min has the same. LCM of 4 and 1 is 4.
Amount that Julian saved
= 8 u - 1 u
= 7 u
7 u = 210
1 u = 210 ÷ 7 = 30
Total savings at first
= 4 u + 1 u
= 5 u
= 5 x 30
= $150
Answer(s): $150
