8+2k=4k+4
8-4=4k-2k I placed the like terms on each side.
4=2k Simplify
4/2=k Leave the variable a side
2 = k
The answer is 1.53x10^10 dollars.
You get this answer by multiplying the total amount of goods in tons (900,000) by the average value of the goods ($17,000 per ton) to get your answer of 1.53x10^10 dollars.
The end behavior of a polynomial function is the behavior of the graph of as approaches positive infinity or negative infinity. The degree and the leading coefficient of a polynomial function determine the end behavior of the graph.
Degree - 3 (odd);
Leading coefficient - 2 (positive).
Then
See attached graph of the function for graphical illustration.
