Answer:
what you need help with?
Step-by-step explanation:
No. Because 33 $ is the money deducted from the 60 $. Dawn bought everything for less than 60 $.
So, if Dawn purchases everything on the rack with a 30% discount and 15% coupon the total will indeed make 45%.
We have to take 100% - 45%= 55% to know the reduction number. Let's proceed to the calculations now.
100%= 60 $
1%=60/100
55%= 60/100 × 55 = 33 $
Now <u>NOTE</u><u>;</u><u> </u><u>33</u><u> </u><u>$</u><u> </u><u>is</u><u> </u><u>the</u><u> </u><u>money</u><u> </u><u>reduced</u><u> </u><u>from</u><u> </u><u>the</u><u> </u><u>60</u><u> </u><u>$</u><u>.</u><u> </u><u>So</u><u>,</u><u> </u><u>logically</u><u>,</u><u> </u><u>33</u><u> </u><u>$</u><u> </u><u>isn't</u><u> </u><u>the</u><u> </u><u>amount</u><u> </u><u>which</u><u> </u><u>Dawn</u><u> </u><u>purchased</u><u> </u><u>the</u><u> </u><u>whole</u><u> </u><u>rack</u><u>. </u>
To find the amount at which she purchased everything, we need to do,
60 $ - 33 $ = 27 $
It is D, not here because they are all dependent.
Step 1. Simplify
![\frac{1}{5} (x+5)](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B5%7D%20%28x%2B5%29)
to
![\frac{x+5}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%2B5%7D%7B5%7D%20)
Step 2. Simplify
![\frac{x+5}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%2B5%7D%7B5%7D%20)
to
![1+ \frac{x}{5}](https://tex.z-dn.net/?f=1%2B%20%5Cfrac%7Bx%7D%7B5%7D%20)
Step 3. Simplify
![\frac{1}{4} (x-3)](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B4%7D%20%28x-3%29)
to
![\frac{x-3}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx-3%7D%7B4%7D%20)
Step 4. Cancel
![1](https://tex.z-dn.net/?f=1)
on both sides
Step 5. Multiply both sides by
![20](https://tex.z-dn.net/?f=20)
(the LCM of
![5,4](https://tex.z-dn.net/?f=5%2C4)
)
Step 6. Expand
Step 7. Subtract
![5x](https://tex.z-dn.net/?f=5x)
from both sides
Step 8. Simplify
![4x-5x](https://tex.z-dn.net/?f=4x-5x)
to
![-x](https://tex.z-dn.net/?f=-x)
Step 9. Multiply both sides by
![-1](https://tex.z-dn.net/?f=-1)
![x=15](https://tex.z-dn.net/?f=x%3D15)
Done! :) Hope this helps! :)
My answer to the question is as follows:
First one looks like you are squaring the number, then multiplying the result by 4, i.e.
<span>y=4<span>x2
</span></span><span>second one is similar, but instead of squaring and multiplying by 4, you are squaring and then dividing by 2
</span>
I hope my answer has come to your help. God bless and have a nice day ahead!
