- $240 |
After |
3 u - $880 |
1 u - $240 |
(a)
The amounts that Jade and Vanessa had in the end are the same.
3 u - 880 = 1 u - 240
3 u - 1 u = 880 - 240
2 u = 640
1 u = 640 ÷ 2 = 320
Amount that Vanessa had at first
= 1 u
= $320
(b)
Amount that Jade had at first
= 3 u
= 3 x 320
= $960
Answer(s): (a) $320, (b) $960
