After |
5 u - $810 |
1 u - $130 |
(a)
The amounts that Kimberly and Winnie had in the end are the same.
5 u - 810 = 1 u - 130
5 u - 1 u = 810 - 130
4 u = 680
1 u = 680 ÷ 4 = 170
Amount that Winnie had at first
= 1 u
= $170
(b)
Amount that Kimberly had at first
= 5 u
= 5 x 170
= $850
Answer(s): (a) $170, (b) $850
