Answer:

  Store A has a better deal because $402.90 is less than $404.10.

Step-by-step explanation:

<u>Store A</u>

The $25 off coupon reduces the price to ...

  $499 - 25 = $474

The discount from this amount is 15%, so is ...

  $474 × 0.15 = $71.10

The final amount paid is then ...

  $474.00 -71.10 = $402.90

(<em>Side note</em>: you can select the correct answer at this point, because only one answer shows this value.)

___

<u>Store B</u>

After the $20 off coupon, the price is ...

  $469 -20 = $449

The additional 10% discount amounts to ...

  $449 × 0.10 = $44.90

So, the final price is ...

  $449.00 -44.90 = $404.10

___

Now, you know that Store A offers the better price because $402.90 is less than $404.10.

He drinks 8 glasses of water in one day. to know the number of glasses he drinks in 365 days, simply use cross multiplication as follows:
number of glasses per year = (365*8)/1 = 2920 glasses
so, yes his assumption is reasonable if he kept the same rate (8 glasses per day each day)

A parabola can be represented by the equation y2 = –x. What are the coordinates of the focus and the equation of the directrix?
Vilka [71]
(y-k)²=4p(x-h)
(h,k) is vertex
and since we got the y term squred, it is facing left or right
when p is positive, then focus is to right of veretx
p is distance from focus to vertex and from vertex to dirextix

y²=-x
(y-0)²=4(-1/4)(x-0)
vertex is (0,0)
p is negative so then focus to left of vertex
so the focus is (-1/4,0)
dirextix is x=1/4
