45 Raeann's money =
46 Gabby's money
Raeann's money : Gabby's money = 5 : 6
(3) = (4)
20 u - 6.4 = 18 u - 3.3
20 u - 18 u = 6.4 - 3.3
2 u = 3.1
1 u = 1.55
Amount Gabby has at first
= 6 u
= 6 x 1.55
= 9.3 (a)
Amount Raeann has in the end
= 5 u - 1.6
= (5 x 1.55) - 1.6
= 6.15 (b)
Answers: (a) $9.30; (b) $6.15
