In a jewllery shop, necklaces are sold as either 18 carat gold, 22 carat gold or 24 carat gold. The number of necklaces in stock in the shop are shown:
18 carat: 40 stock
22 carat: -
24 carat: 20 stock
25% of the stocks of necklaces are 22 carat
How many 22 carat necklaces are there in stock in the shop?
Is the answer 15, I ain't too sure!
Let x be the number of 22 carat necklaces.
x = (1/4)(40 + x + 20)
= x/4 + 15/4
3x/4 = 15/4
x = 15
Yes, your answer is right.
To find the number of 22-carat necklaces in stock, we can use the information given that 25% of the total necklace stocks are 22 carat.
1. Start by finding the total number of necklaces in stock. From the information provided, we know that the sum of the stocks of 18, 22, and 24-carat necklaces is 40 + 20 = 60.
2. Calculate 25% of the total number of necklaces in stock by multiplying the total number of necklaces (60) by 0.25: 60 * 0.25 = 15.
Therefore, there are 15 22-carat necklaces in stock in the shop. Hence, your answer is correct!
