Question

Suppose the cost per ton f(x) to build an oil platform of x thousand tons is approximated byf(x)= 62,500 ______ x+125What is the cost per ton for x=30?

Answer 1

Given that

The cost per ton f(x) to build an oil platform of x thousand tons is approximated by

`f(x)=(62500)/(x+125)`

The cost per ton for x = 30, i.e f(30) will be

`\begin{gathered} f(x)=(62500)/(x+125) \\ f(30)=(62500)/(x+125)=(62500)/(30+125)=(62500)/(155) \\ f(30)=(62500)/(155)=403.226\text{ (3 d.p)} \\ f(30)=403.226\text{ (3 d.p)} \end{gathered}`

Hence, the answer is 403.226 (3 d.p)
