A store marks up a laptop 50% from its original price of $299. What is the new price for the computer? $448.50
$149.50
$597.50
$300.50

$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!

step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
