Last week, Anna had twice as much savings as Jack. This week, Jack saves $600. As a result, he now has thrice as much savings as Anna. What is their total savings now?

2 u |
1 u |

+ $600 |

| After |
1x2 =
2 u |
3x2 =
6 u |
8 u |
The amount of savings that Anna has at first and in the end remains unchanged. Make the amount of savings that Anna has the same. LCM of 2 and 1 is 2.
Amount that Jack saved
= 6 u - 1 u
= 5 u
5 u = 600
1 u = 600 ÷ 5 = 120
Total savings now
= 2 u + 6 u
= 8 u
= 8 x 120
= $960
Answer(s): $960
