Answer:
![c(x) = 225 + 3.50x](https://tex.z-dn.net/?f=c%28x%29%20%3D%20225%20%2B%203.50x)
The amazon stock increases 21 units during the first 6 hours.
Step-by-step explanation:
We are given the following in the question:
Value of share of Amazon stock = 225 units
Rate of increase of stock = 3.50 units per hour during the first six hours
Thus, the value of share stock can be given by the equation:
![c(x) = 225 + 3.50x](https://tex.z-dn.net/?f=c%28x%29%20%3D%20225%20%2B%203.50x)
where x is the number of hours.
During first six hours, the value of stock is given by putting x = 6 in the equation:
![c(6) = 225 + 3.50(6) = 246](https://tex.z-dn.net/?f=c%286%29%20%3D%20225%20%2B%203.50%286%29%20%3D%20246)
Increase during first 6 hours =
![=c(6) - c(0)\\=246-225\\=21](https://tex.z-dn.net/?f=%3Dc%286%29%20-%20c%280%29%5C%5C%3D246-225%5C%5C%3D21)
Thus, the amazon stock increases 21 units during the first 6 hours.

Answer:
The original price of the book was $12.50
Step-by-step explanation:
3x - 0.2(3x) + 10 = 40
30x - 2(3x) + 100 = 400
30x - 6x + 100 = 400
24x + 100 = 400
24x = 300
x = 12.50
