a boat is marked up to 20% on the original price. The original price was $50 what is the sales price of the boat before sales tax?

60 dollars.

Step-by-step explanation:

Markup is nothing but the difference between the selling price of a good or service and its cost. It is expressed as a percentage above the cost. In short, we can say that it is the added price over the total cost of the good or service that provides the seller with a profit.

Original price = 50 dollars

ADD: 20% on original price = Markup price = 50 (20/100) = 10 dollars

Hence Sales price = 50+10 = 60 dollars
