Answer:
A) The selling price for each necklaces is $8.625
B) The profit mark in each necklaces is 15%
Step-by-step explanation:
Given as :
The total cost of two necklaces = c.p = $15
The markup percentage for the necklaces = m = 15%
Let The selling price for both necklaces = s.p
A ) <u>Now, From markup method</u>
m% = 
or, 15% = 
or, 15% =
- 1
or,
= 1 + 15%
or,
= 1 + 
or,
= 
or,
= 
∴ s.p = 
I.e s.p = $17.25
So, selling price of two necklaces = s.p = $17.25
or, selling price of one necklaces = s.p =
= $8.625
Hence, The selling price for each necklaces is $8.625
<u>Now, Again</u>
B) ∵ The total cost of two necklaces = c.p = $15
So, The cost price of one necklaces =
= $7.5
∴ profit% for each necklace = 
i.e profit% for each necklace = 
Or, profit% for each necklace = 
Or, profit% for each necklace = 0.15
So, The profit make in each necklaces = 15%
Hence, The profit mark in each necklaces is 15%
