A boat is marked up 20% on the original price. The original price was $50. What is the sale price of the boat before sales tax?

The marked up price was $60 because $50 times 0.2 = $10 and $50 + $10 = $60.

So,

The original price was $50.

The price was increased by 20%.

If you find 20% of $50 and add the result to $50, you will get the markup price.

20% - - > 0.2

50 (.2) = $10

10 + 50 = 60

The marked-up price of the boat is $60.
