Adele share :

b)

Barbara share :

Collette share :

c)

    $            €

 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
