Sarah decides to shop online at Hudson's Bay for some items. She buys a set of skis for $75.99, a pair of ski gloves for $25.00, 5 pairs of thermal socks, for each pair costing $12.00 and boots for $130.00. If there was a discount of the skis, 50% off. Then what was the sale price? What is the total cost of these items without discount ? And finally What was the total cost of the items including discounts?

Sale price of skies = $113.99

               Items cost without discount =$328.99

                Total cost of items with discount= 290.99

Step-by-step explanation:

First lets find the sale price of skies  

75.99*1.50=113.99

113.99+25+60+130

$328.99 ( price without discount)

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
