- $100 |
After |
4 u - $880 |
1 u - $100 |
(a)
The amounts that Julie and Kylie had in the end are the same.
4 u - 880 = 1 u - 100
4 u - 1 u = 880 - 100
3 u = 780
1 u = 780 ÷ 3 = 260
Amount that Kylie had at first
= 1 u
= $260
(b)
Amount that Julie had at first
= 4 u
= 4 x 260
= $1040
Answer(s): (a) $260, (b) $1040
