Answer:
$63.45
Step-by-step explanation:
first, find 470% of 15. 470*15=$70.50. then, find 10% of it. 70.50 divided by 10 = $7.05. then subtract it from the new price to get the final price. 70.50 - 7.05 = $63.45
Given:
![\dfrac{1}{4}\text{ to }\dfrac{1}{2}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B4%7D%5Ctext%7B%20to%20%7D%5Cdfrac%7B1%7D%7B2%7D)
To find:
The percent of change, round to the nearest 10th of a percent.
Solution:
We have,
Initial value = ![\dfrac{1}{4}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B4%7D)
New value = ![\dfrac{1}{2}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B2%7D)
We know that, the percentage change is
![\%\text{ change}=\dfrac{\text{New value - Initial value}}{\text{Initial value}}\times 100](https://tex.z-dn.net/?f=%5C%25%5Ctext%7B%20change%7D%3D%5Cdfrac%7B%5Ctext%7BNew%20value%20-%20Initial%20value%7D%7D%7B%5Ctext%7BInitial%20value%7D%7D%5Ctimes%20100)
Putting the given values, we get
![\%\text{ change}=\dfrac{\dfrac{1}{2}-\dfrac{1}{4}}{\dfrac{1}{4}}\times 100](https://tex.z-dn.net/?f=%5C%25%5Ctext%7B%20change%7D%3D%5Cdfrac%7B%5Cdfrac%7B1%7D%7B2%7D-%5Cdfrac%7B1%7D%7B4%7D%7D%7B%5Cdfrac%7B1%7D%7B4%7D%7D%5Ctimes%20100)
![\%\text{ change}=\dfrac{\dfrac{2-1}{4}}{\dfrac{1}{4}}\times 100](https://tex.z-dn.net/?f=%5C%25%5Ctext%7B%20change%7D%3D%5Cdfrac%7B%5Cdfrac%7B2-1%7D%7B4%7D%7D%7B%5Cdfrac%7B1%7D%7B4%7D%7D%5Ctimes%20100)
![\%\text{ change}=\dfrac{\dfrac{1}{4}}{\dfrac{1}{4}}\times 100](https://tex.z-dn.net/?f=%5C%25%5Ctext%7B%20change%7D%3D%5Cdfrac%7B%5Cdfrac%7B1%7D%7B4%7D%7D%7B%5Cdfrac%7B1%7D%7B4%7D%7D%5Ctimes%20100)
![\%\text{ change}=1\times 100](https://tex.z-dn.net/?f=%5C%25%5Ctext%7B%20change%7D%3D1%5Ctimes%20100)
![\%\text{ change}=100\%](https://tex.z-dn.net/?f=%5C%25%5Ctext%7B%20change%7D%3D100%5C%25)
Here, the % change is positive, it represents the percent increase.
Therefore, the percent of change is 100% of increase.
Answer:Each Y could equal 12
Step-by-step explanation:
You would divide each side of the equation y 3 to get y^2=144.
Next take the root of both sides to get y= ± 12
After that just separate the solutions and get 12.
