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 ) Now, From markup method
m% = [tex]\dfrac{s.p - c.p}{c.p}[/tex]
or, 15% = [tex]\dfrac{s.p - 15}{15}[/tex]
or, 15% = [tex]\dfrac{s.p}{15}[/tex] - 1
or, [tex]\dfrac{s.p}{15}[/tex] = 1 + 15%
or, [tex]\dfrac{s.p}{15}[/tex] = 1 + [tex]\dfrac{15}{100}[/tex]
or, [tex]\dfrac{s.p}{15}[/tex] = [tex]\dfrac{100 + 15}{100}[/tex]
or, [tex]\dfrac{s.p}{15}[/tex] = [tex]\dfrac{115}{100}[/tex]
∴ s.p = [tex]\frac{15\times 115}{100}[/tex]
I.e s.p = $17.25
So, selling price of two necklaces = s.p = $17.25
or, selling price of one necklaces = s.p = [tex]\dfrac{17.25}{2}[/tex] = $8.625
Hence, The selling price for each necklaces is $8.625
Now, Again
B) ∵ The total cost of two necklaces = c.p = $15
So, The cost price of one necklaces = [tex]\dfrac{15}{2}[/tex] = $7.5
∴ profit% for each necklace = [tex]\dfrac{s.p - c.p}{c.p}[/tex]
i.e profit% for each necklace = [tex]\dfrac{8.625 - 7.5}{7.5}[/tex]
Or, profit% for each necklace = [tex]\dfrac{1.125}{7.5}[/tex]
Or, profit% for each necklace = 0.15
So, The profit make in each necklaces = 15%
Hence, The profit mark in each necklaces is 15%
