45 Hilda's money =
23 Julie's money
45 Hilda's money =
46 Julie's money
Hilda's money : Julie's money = 5 : 6
(3) = (4)
15 u - 6.3 = 12 u - 1.8
15 u - 12 u = 6.3 - 1.8
3 u = 4.5
1 u = 1.5
Amount Julie has at first
= 6 u
= 6 x 1.5
= 9 (a)
Amount Hilda has in the end
= 5 u - 2.1
= (5 x 1.5) - 2.1
= 5.4 (b)
Answers: (a) $9.00; (b) $5.40
