45 Raeann's money =
46 Elyse's money
Raeann's money : Elyse's money = 5 : 6
(3) = (4)
20 u - 10 = 18 u - 2.1
20 u - 18 u = 10 - 2.1
2 u = 7.9
1 u = 3.95
Amount Elyse has at first
= 6 u
= 6 x 3.95
= 23.7 (a)
Amount Raeann has in the end
= 5 u - 2.5
= (5 x 3.95) - 2.5
= 17.25 (b)
Answers: (a) $23.70; (b) $17.25
