Last month, Tiffany had twice as much savings as Pierre. This month, Pierre saves $700. As a result, he now has four times as much savings as Tiffany. What is their total savings now?

| After |
1x2 =
2 u |
4x2 =
8 u |
10 u |
The amount of savings that Tiffany has at first and in the end remains unchanged. Make the amount of savings that Tiffany has the same. LCM of 2 and 1 is 2.
Amount that Pierre saved
= 8 u - 1 u
= 7 u
7 u = 700
1 u = 700 ÷ 7 = 100
Total savings now
= 2 u + 8 u
= 10 u
= 10 x 100
= $1000
Answer(s): $1000
