Answer:
Ellen will pay $16.22 for the book.
Step-by-step explanation:
Part 1:
We know that the book Ellen wants to buy has a normal price of $18. However, there is a 15% discount. So, let's calculate 15% of $18.
18 x 0.15 = $2.70
This lets us know that there is a $2.70 discount.
Now, let's subtract the discount from the regular price.
18 - 2.70 = $15.30
So, now we know the discounted price is $15.30
Part 2:
We also know that Ellen has to pay 6% sales tax. The discounted price is 100% of the price, plus 6% is 106%. Let's calculate the tax to figure out the total amount.
15.30 x 1.06 = $16.22 when rounded to the nearest cent.
Therefore, Ellen will pay the total amount of $16.22.
First, look at the digits less than one one-hundredth (
![\frac{1}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B100%7D)
, or .01):
0.00416
See if that number is closer to the higher or lower hundredth:
(if the first digit is 5 or greater, then higher;
if the first digit is 4 or lower, then lower)
Since 4 is closer to the lower hundred, round down
0.00416 -> 0.00000
Add this to the digits we didn't touch:
<span>17,546.32000 + 0.00000 = 17,546.32
</span>17,546.32416 rounded to the nearest hundredth is
C. <span>
17,546.32</span>
The shortest hand stands for one hour. to find the hour look to where the shortest hand is pointing to or has not passed yet.
the long hand stands for minutes. multiply 5 by the number that the longest hand is pointing to or has not passed yet, then count how many dashes after that number to find the minute. 12 stands for 0 in minutes.

don't worry, i had trouble with this too when i was younger. you will get it eventually. hope i helped! ;)
Answer:
![y = 2x - 5](https://tex.z-dn.net/?f=y%20%3D%202x%20-%205)
Explanation:
Slope-intercept form formula:
![y = mx + b](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20b)
For this formula we need the slope to find the slope use the slope formula:
![\frac{y_{2} - y}{x_{2} - x}](https://tex.z-dn.net/?f=%5Cfrac%7By_%7B2%7D%20-%20y%7D%7Bx_%7B2%7D%20-%20x%7D)
Plug in the two points (1,-3) and (3,1)
![\frac{4}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B2%7D%20)
=2
the slope is 2
Now use the slope-interpect formula and plug in the slope (m)
![y = 2x + b](https://tex.z-dn.net/?f=y%20%3D%202x%20%2B%20b)
plug in one point I'll use (3,1)
![1 = 2(3) + b](https://tex.z-dn.net/?f=1%20%3D%202%283%29%20%2B%20b)
1 = 6 +b
1-6=6-6+b
-5 = b
The equation would be:
