Zara and Peter had the same amount of savings at first. Then Zara spent
17 of her savings and Peter spent
34 of his savings. If Zara spent $1394 less than Peter, how much did each of them have at first?

Zara |
Peter |
| Before |
7x4 =
28 u |
4x7 =
28 u |
| Change |
1x4 =
- 4 u |
3x7 =
- 21 u |
| After |
24 u |
7 u |
The amount that Zara and Peter had at first is the same. Make the amount that Zara and Peter each had the same. LCM of 7 and 4 is 28.
Amount that Zara spent less than Peter
= 21 u - 4 u
= 17 u
17 u = 1394
1 u = 1394 ÷ 17 = 82
Amount that each of them had at first
= 28 u
= 28 x 82
= $2296
Answer(s): $2296
