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

AnnyKZ [126]

Answer:

$60

Step-by-step explanation:

We can create a proportion to find the markup from original price to the marked up price. A proportion is an equation where two ratios are set equal to each other. We create two fractions using the prices and percents. It is marked up by 20% so we pay 120% of $50.

$\frac{120}{100} =\frac{x}{50}$
