35 Natalie's money =
23 Hilda's money
610 Natalie's money =
69 Hilda's money
Natalie's money : Hilda's money = 10 : 9
(3) = (4)
50 u - 8 = 18 u - 1.6
50 u - 18 u = 8 - 1.6
32 u = 6.4
1 u = 0.2
Amount Hilda has at first
= 9 u
= 9 x 0.2
= 1.8 (a)
Amount Natalie has in the end
= 10 u - 1.6
= (10 x 0.2) - 1.6
= 0.4 (b)
Answers: (a) $1.80; (b) $0.40
