The amount added to the original price of the jewelery is the Markup price. Hence, the amount added is $16.34

  • Markup = 57% = 0.57
  • Cost of jewellery = c
  • Retail price = $45

Retail price = cost of jewellery + Markup

$45 = c + 0.57c

45 = 1.57c

Divide both sides by 1.57

c = 45/1.57

c = $28.66

The Markup price = (Retail price - Original price)

  • Markup = $45 - $28.66 = $16.34

Therefore, the amount added to the original price is $16.34
