Answer

1. **Calcul du prix après la réduction:**<br /><br />La réduction est de 20% de 8,75$. On calcule le montant de la réduction : 8,75$ * 0,20 = 1,75$<br /><br />On soustrait la réduction du prix original : 8,75$ - 1,75$ = 7,00$<br /><br />Le prix du cadenas après la réduction est donc de 7,00$.<br /><br />2. **Calcul de la taxe de vente:**<br /><br />La taxe de vente est de 7% du prix réduit. On calcule le montant de la taxe : 7,00$ * 0,07 = 0,49$<br /><br />3. **Calcul du coût total:**<br /><br />On additionne le prix réduit et la taxe de vente : 7,00$ + 0,49$ = 7,49$<br /><br />Le coût total du cadenas est donc de 7,49$.<br /><br />**Réponse:** 7,49$<br />
