Nonamiya [84]

Answer:

a. The number of custom necklaces that can be manufactured if each requires 2 7/8 ounces of gold is 74 necklaces.

b. The value of the gold in each necklace is $1761

Step-by-step explanation:

(a) Number of necklaces

27/8 ounces of gold=2.875

No of necklaces=212.75oz x 1 necklaces/2.875oz

                          =74 necklaces

Pure 24K gold is worth $1050/oz.

Value of pure gold=1.677oz x 1050/1oz

The value of the gold in each necklace is $1761
