Answer:
8.50
Step-by-step explanation:
Retail price = original price + markup
markup = original price * markup percent
Retail price = original price + original price * markup percent
Factor out the original price
Retail price = original price(1+ markup percent)
We know the retail price and the markup percent
17.85 = original price (1+110%)
Change to decimal form
17.85 = original price (1+1.10)
17.85 = original price (2.10)
Divide each side by 2.10
17.85/2.10 = original price *2.10/2.10
8.50 = original price
