In a college parking lot, the number of ordinary cars is larger than the number of sport utility vehicles by 77.3%. the differen
mezya [45]

Let x be the number of ordinary cars

Let y be the number of SUV's

The difference between the number of ordinary cars and the number of suvs is 17.

So x-y=17 ----> first equation

The number of ordinary cars is larger than the number of sport utility vehicles by 77.3%.

ordinary cars = SUV + 77.3% of SUV

x = y + 0.773y

x = 1.773y

Now we solve for y

We plug in x=1.773y in first equation

1.773y - y=17

0.773y = 17

y = 21.9922

Number of SUV's = 22

Monsieur Anatole est un artisan spécialiser dans la fabrication de colliers. Il dispose 3 717 perles rouges et de 2 205 perles b
djyliett [7]

Answer:

Sur la vente d'un collier, l'artisan qui a fait le meilleur profit était Monsieur Bernard

Step-by-step explanation:

a) Pour Monsieur Anatole

Nous trouvons le plus grand diviseur commun de 3717 et 2205

Par conséquent, le plus grand diviseur commun = 63

Le nombre de colliers qu'il a fabriqués = 63

Découvrir combien de perles rouges et blanches il a utilisées

Pour les perles rouges =

= 3717/63 = 59 perles

Pour les perles blanches

= 2205/63 = 35 perles blanches

il fabrique 63 colliers avec 59 perles rouges et 35 perles blanches

On nous dit dans la question que:

Les deux artisans décident de fixer le prix de vente de chaque collier selon la constitution, à savoir: 22 centimes d'euro par perle rouge et 13 centimes par perle blanche.

Le prix de vente du collier =

0,22 × 59 + 0,13 × 35 = 17,53 €

Prix ​​de revient = 9,84 €

Le profit est calculé comme suit:

17,53 € - 9,84 € = 7,69 €

Nous calculons le pourcentage de profit

= Bénéfice / Prix de revient × 100

= 7,69 / 9,84 × 100

= 78,150406504%

= 78,2%

b) Pour Monsieur Bernard

Le GCD de 1472 et 2898 = 46

Par conséquent, il a fait 46 colliers

Le nombre de perles rouges = 1472/46

= 32 perles rouges

Le nombre de perles blanches = 2898/46

= 63 perles blanches

Les deux artisans décident de fixer le prix de vente de chaque collier selon la constitution, à savoir: 22 centimes d'euro par perle rouge et 13 centimes par perle blanche.

Le prix de vente de chaque colliers = 32 × 0,22 + 63 × 0,13 = 15,23 €

Le coût Prix du collier = 8,48 € chacun

Le profit qu'il a réalisé = 15,23 € - 8,48 €

= 6,75 €

Nous calculons le pourcentage de profit

= Bénéfice / Prix de revient × 100

= 6,75 / 8,48 × 100

= 79,5990566%

= 79,6%

Sur la vente d'un collier, l'artisan qui a fait le meilleur profit était Monsieur Bernard
