Create an item with a selling price over $100 a discount of 25% and tax is 9%
Lana71 [14]

First, convert the 25% to a real mathematical number. For percents, this is always done by dividing the 25% by 100%, or 25% / 100% = 0.250.

Second, find out what 25% of $100 is. This is the amount of the sale discount. This is always found by mulitplying 0.250 by the item's cost $100, like this:

0.250 x $100 = $25.00.

So for this sale, you'll save $25.00 on this item.

This means, the cost of the item to you is

$100 - $25.00 = $75.00.

Alternatively, you can think about it this way. The item is 25% off. This means you'll pay 75.000% of the total cost (100% - 25% = 75.000%).

Now what's 75.000% of the total cost?

0.750 x $100 = $75.00.

Just like the result above, the sale price on the item is $75.00.

Hope this helps you on your assignment! :)

PLSS HELPP BRAINLIEST AND 65 POINTS <br> pls do the graph too
Eddi Din [679]

Answer:

\Large \boxed{ -x+65}

Step-by-step explanation:

Two points are (0, 65) and (10, 55)

Calculate slope <em>m</em>

\displaystyle m=\frac{y_2 - y_1}{x_2 - x_1}

\displaystyle m=\frac{55-65}{10-0}=-1

Use slope-intercept form

y=mx+b

y=-1x+b

<em>b</em>  is the y-intercept, y-intercept is (0,65)

y=-1x+65
