Last month, Natalie had twice as much savings as Owen. This month, Owen saves $630. As a result, he now has four times as much savings as Natalie. What is their total savings now?

+ $630 |

| After |
1x2 =
2 u |
4x2 =
8 u |
10 u |
The amount of savings that Natalie has at first and in the end remains unchanged. Make the amount of savings that Natalie has the same. LCM of 2 and 1 is 2.
Amount that Owen saved
= 8 u - 1 u
= 7 u
7 u = 630
1 u = 630 ÷ 7 = 90
Total savings now
= 2 u + 8 u
= 10 u
= 10 x 90
= $900
Answer(s): $900
