45 Roshel's money =
23 Fanny's money
45 Roshel's money =
46 Fanny's money
Roshel's money : Fanny's money = 5 : 6
(3) = (4)
20 u - 7.6 = 18 u - 3.6
20 u - 18 u = 7.6 - 3.6
2 u = 4
1 u = 2
Amount Fanny has at first
= 6 u
= 6 x 2
= 12 (a)
Amount Roshel has in the end
= 5 u - 1.9
= (5 x 2) - 1.9
= 8.1 (b)
Answers: (a) $12.00; (b) $8.10
