Question 24664
Your silver necklace is worth $45.50 and the sale price is for 1/5 off.  First you should find out how much is 1/5.

If you divide 5 into 1 you will get .2 this is your percentage off.  

Then you take your silver necklace price of $45.50 and multiply it by your percentage of .2 which will give you $9.10.

$45.50 - $9.10 = $36.40 is what you would pay for this silver necklace.
