A store marks up a laptop 50% from its original price of $299. What is the new price for the computer?

Answer:

$448.50

Step-by-step explanation:

"Marking up" an item by x% means to increase its price by x% of the original price.

Here, when marking up by 50%, you would multiply the original price by 1.5:

1.5*299 = $448.50

You wouldn't just multiply by .5 because that would only give you 50% of $299. You could multiply .5*299 and get $149.5, but then you'd have to add it to $299, which would get you $448.50 again!

The quicker way is to just multiply the original price by 1+x%.

Hope this helps!

Hamburger sells 3 pounds for six dollars if Samantha 510 pounds of hamburger how much will she pay
Lina20 [59]
I believe you meant to say that if Samantha bought 510 pounds of hamburger, how much will she pay?
 
Now from the information we already have, we know that 3 pounds of hamburger will cost 6 dollars. 

The next thing we need to know is how much one pound of hamburger will cost. This will help us calculate  how much the rest will cost.

we now form an equation to assist us.
3 = 6
1= x

(where x represents the unknown price of one pound of hamburger)

Now we must cross-multiply:

3 * x = 6 x 1

3x = 6 

x = 6/3

x = 2

therefore one pound of hamburger costs 2 dollars.

Now, If one pound costs 2 dollars, how about 510 pounds?

We simply multiply:  510 x 2 = 1,020

Therefore  Samantha will pay 1, 020 dollars for 510 pounds of hamburger.
