Answer:
$408
Step-by-step explanation:
What we know:
John earns a 3% commission for every car he sells.
He sold a car today for $13,600.
Multiply 3/100 by 13,600 to get your answer.
3/100 * 13600
40800/100
$408 in commission
Not sure when this is from but if it was recent and you still need the answer I believe it’s 1/5.
Given:

where,
.
To find:
The value of
.
Solution:
We have,

Differentiate with respect to x.

Using chain rule, we get

Now, put x=5.

![[\because g(5)=-1,g'(5)=8]](https://tex.z-dn.net/?f=%5B%5Cbecause%20g%285%29%3D-1%2Cg%27%285%29%3D8%5D)
![[\because f'(-1)=3]](https://tex.z-dn.net/?f=%5B%5Cbecause%20f%27%28-1%29%3D3%5D)

Therefore, the value of
is 24.
Step 2 is wrong and i don't know the other question
