Bonjour,
Exercice 29
a) Une bouteille en cl → C = 75 + x
6 bouteilles → C = 6(75 + x) ou bien C = 450 + 6x
b) Pour
x = 15
→ C = 75 + 15 =
90 cl
Dans un pack de 6 bouteilles → C = 6(75 +15) = 450 + 90 cl =
540 cl
Pour
x = 20
→ C = 75 + 20 =
95 cl
Dans un pack de
6 bouteilles
→ C = 6(75 + 20) = 450 + 120 =
570 cl
Exercice 30
