Answer:
The explicit formula that will be used to find the cost of cleaning up d day oil spill is:
[tex]CoS(d)=532.5d+2[/tex]
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:
[tex]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[/tex]
