35 Elyse's money =
23 Wendy's money
610 Elyse's money =
69 Wendy's money
Elyse's money : Wendy's money = 10 : 9
(3) = (4)
40 u - 7.6 = 27 u - 2.4
40 u - 27 u = 7.6 - 2.4
13 u = 5.2
1 u = 0.4
Amount Wendy has at first
= 9 u
= 9 x 0.4
= 3.6 (a)
Amount Elyse has in the end
= 10 u - 1.9
= (10 x 0.4) - 1.9
= 2.1 (b)
Answers: (a) $3.60; (b) $2.10
