Answer 1

`c(x) = 225 + 3.50x`

The amazon stock increases 21 units during the first 6 hours.

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`

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`

Increase during first 6 hours =

`=c(6) - c(0)\\=246-225\\=21`

Thus, the amazon stock increases 21 units during the first 6 hours.
