Astore offers customers a 30 % discount on the price x of selected items. then, the store takes off an additional 15 % off at the cash register. write a price function p ( x ) that computes the final price of the item in terms of the original price x .

The price function expressed in terms of x, after the two discount of 30% and 15% is 0.595x

Price after first discount = (100% of x) - (30% of x)

Price after first discount = x - 0.3x = 0.7x

Second discount :

Price after second discount = 0.7x - (0.15 × 0.7x)

Price after second discount = 0.7x - 0.105x = 0.595x

Therefore, the price function, P(x) = 0.595x

P(x) = 0.595x

Step-by-step explanation:

A store offers customers a a 30% discount on the price x of an item.

Therefore, after 30% discount selling price of the item = [x - (30% of x)]

= (x - 0.30x)

= 0.70x

Then the store takes off an additional 15% off on the same item then the final selling price of the given item will be = 0.70x - (15% of 0.70x)

= (0.70x - 0.105x)

= 0.595x

And the function that represents the final selling price will be

P(x) = 0.595x

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
