Answer
Find out the what is the unit cost .
To prove
As given
A 50in link of silver chain cost $82.99 .
[tex]Unit\ cost\ of\ silver\ chain = \frac{Cost\ of\ 50in\ link\ of\ silver\ chain}{Total\ length\ of\ silver\ chain}[/tex]
[tex]Unit\ cost\ of\ silver\ chain = \frac{82.99}{50}[/tex]
Unit cost of silver chain = $1.6598
As given
A 15 inch length of gold chain cost $112.59
[tex]Unit\ cost\ of\ silver\ chain = \frac{Cost\ of\ 15in\ link\ of\ gold\ chain}{Total\ length\ of\ gold\ chain}[/tex]
[tex]Unit\ cost\ of\ silver\ chain = \frac{112.59}{15}[/tex]
Unit cost of silver chain = $ 7.51 (Approx)
Therefore the unit cost of the silver chain is $1.6598 and the unit cost of the gold chain is $7.51 .
