Sophie fabrique et vend des chandelles faites de cire d'abeille. Ses deux
demiers modèles sont des prismes étoiles semblables. Le rapport des côtés
des étoiles est de La grande chandelle a une hauteur de 20 cm et le côté
de sa base mesure
5 cm. La petite chandelle nécessite 18 cm de cire.
La cire d'abeille se vend en bâton de 12 cm° 0,80 $ et la surface latérale des
chandelles est emballée dans une pellicule plastique coûtant 0,02 $/100 cm?.
Sophie aimerait vendre 100 unités du grand modèle et 125 unités du petit
modèle au coût de 18 $ et 12 $ respectivement
Sophie peut-elle espérer faire un profit de 2 500 $ si elle réussit à vendre
le nombre de chandelles souhaité ?
