Réponse :
Kevin bought 50 biscuits .
Explications :
Bonjour ,
Prenons exemple si Kevin avait 0 biscuits
Il en mange 12 ( -12 )
Il en donne 13 a sa sœur ( -13 )
Et 5 a son ami ( -5 )
Mais son père lui en donne 3 ( +3 )
-12-13-15 = -30
-30 + 3 = -27
Combien de biscuit il aurait fallu pour avoir 23 ?
-27 + 50 = 23
Kevin a donc acheter 50 biscuits
En espérant t'avoir aider ; bonne journée .
