Given:
![f(x)=\sqrt[]{5x^2-2}](https://tex.z-dn.net/?f=f%28x%29%3D%5Csqrt%5B%5D%7B5x%5E2-2%7D)
f(X) will be differentiated by chain rule.
There are 150 9th graders and 300 10th graders
100 = 40 + 3x
Subtract 40 from each side
60 = 3x
Divide each side by 3
20 = x
The highest price of a sweatshirt can be $20
100 = 40 + 3(20)
Answer:
135
Step-by-step explanation:
Given:
