**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%**
