So we always make the denominator (bottom number) the same, then when it’s the same we just add!
The maximum and minimum percent of students who write their notes with a pencil are 22% and 25%, respectively
<h3>Survey</h3>
The survey results given as:
--- the proportion of students reported that they wrote their notes with a pencil
![Accuracy = 3\%](https://tex.z-dn.net/?f=Accuracy%20%3D%203%5C%25)
<h3>Range</h3>
The range is then calculated as:
![Range = Pencil \pm Accuracy](https://tex.z-dn.net/?f=Range%20%3D%20Pencil%20%5Cpm%20Accuracy)
<h3>Minimum</h3>
So, we have:
![Minimum = Pencil - Accuracy](https://tex.z-dn.net/?f=Minimum%20%3D%20Pencil%20-%20Accuracy)
This gives
![Minimum = 25\% - 3\%](https://tex.z-dn.net/?f=Minimum%20%3D%2025%5C%25%20-%203%5C%25)
![Minimum = 22\%](https://tex.z-dn.net/?f=Minimum%20%3D%2022%5C%25)
<h3>Maximum</h3>
Also, we have:
![Maximum = Pencil + Accuracy](https://tex.z-dn.net/?f=Maximum%20%3D%20Pencil%20%2B%20Accuracy)
This gives
![Maximum = 25\%+ 3\%](https://tex.z-dn.net/?f=Maximum%20%3D%2025%5C%25%2B%203%5C%25)
![Maximum = 28\%](https://tex.z-dn.net/?f=Maximum%20%3D%2028%5C%25)
Hence, the maximum and minimum percent of students who write their notes with a pencil are 22% and 25%, respectively

Step-by-step explanation:
<u>Complete Question:</u>
<em>Ben is 4 times as old as Ishaan. 6 years ago, Ben was 6 times as old as Ishaan. How old is Ishaan now?</em>
<em />
Let Ben's age be "b" and Ishaan's age be "i"
Since Ben is 4 times as Ishaan, we can write:
b = 4i
Ben was 6 times as Ishaan, BUT 6 years ago, we setup the equation like shown below:
b - 6 = 6(i - 6)
Multiplying, we have:
![b - 6 = 6(i - 6)\\b-6=6i-36](https://tex.z-dn.net/?f=b%20-%206%20%3D%206%28i%20-%206%29%5C%5Cb-6%3D6i-36)
Now, we replace b with "4i" and solve for i (Ishaan's age now):
![b-6=6i-36\\4i-6=6i-36\\2i=30\\i=\frac{30}{2}\\i=15](https://tex.z-dn.net/?f=b-6%3D6i-36%5C%5C4i-6%3D6i-36%5C%5C2i%3D30%5C%5Ci%3D%5Cfrac%7B30%7D%7B2%7D%5C%5Ci%3D15)
Ishaan is now 15 years old
64< 67< 125
64^ (1/3) < 67 ^ (1/3) < 125^ (1/3)
4 < 67^ (1/3) < 5
