$ €
1.125 1
306 x
[cross multiply]
x = €272
Adele receives = €272
d)
Apple Cost
1 kg 2.69
5 kg y
y = 2.69 x 5 = $13.45
Cost of 5kg of apples = $13.45
Cost of 3 kg bananas = 17.56 - 13.45 = $4.11
Banana Cost
3kg 4.11
1 kg z
z = $1.37
Cost per kilogram of banana = $1.37
e) Collette share = $136
Half of it on clothes = (1/2) x 136 = $68
(1/5) of her share on books = (1/5) x 136 = 27.20
Balance amount with her = 136 - 27.20 - 68 = $ 40.80
