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?

Answers

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.

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

What is the percent decrease from 60 to 39?

Answers

Answer: 35%

Step-by-step explanation: To find the percent decrease, we use the following formula.

$(Amount-of-change)/(original-number)$

The amount of change is the difference between the two numbers which in this case is 60 - 39 and the first number is 60.

$(60 - 39)/(60)$

60 - 39 is 21 so we are left with 21/60.

60 divided into 21 .35 times. However, our problem is asking for the percent which means we can move the decimal point two places to the right to get 35.

Therefore, the percent decrease is 35%.

$That\ is\ a\ decrease\ of\ \boxed{35}\ percent.$
