Exercice 2 :
Manteau :
180 x 0.25 = 45 , 180-45 = 135
Blouson cuir :
396 x 0.25 = 99 , 396 - 99 = 297
Pantalon :
64 x 0.25 = 16 , 64 - 16 = 48
Jupe :
32 x 0.25 = 8 , 32 - 8 = 24
Pull :
49 x 0.25 = 12,25 , 49 - 12.25 = 36.75
Chemise :
53 x 0.25 = 13.25 , 53 - 13.25 = 39.75
Exercice 3 :
20% : 69 x ( 1 - 0.20 ) = 55.20
10% : 55 x ( 1 - 0.10 ) = 49.50
20% : 85 x ( 1 - 0.20) = 68
15% : 600 x ( 1 - 0.15 ) = 599.1
25% : 152 x ( 1 - 0.25 ) = 151.62
50% : 68 x ( 1 - 0.5 )= 34
