Answer 2

Answer:

The explicit formula that will be used to find the cost of cleaning up d day oil spill is:

                  $CoS(d)=532.5d+2$

Step-by-step explanation:

The amount of oil, S, in tons, that has been spilled in d days is given by the function:

             S(d)=355d.

The cost to clean a t ton oil spill can be modeled by the function:

                       C(t)=1.5t+2

This means that the cost to clean in d days is given  by the composition function:    

 $CoS(d)=C(S(d))\\\\\\i.e.\\\\\\CoS(d)=C(355d)\\\\\\i.e.\\\\\\CoS(d)=1.5(355d)+2\\\\\\i.e.\\\\\\CoS(d)=532.5d+2$
