Answer:
[tex]\boxed{7k + 3}[/tex]
Step-by-step explanation:
Average cost = total cost/number of items = (35k² + 29k + 6)/(5k + 2)
Perhaps the best way to solve this problem is to use long division.
7k + 3
5k + 2)35k² + 29k + 6
35k² + 14k
15k + 6
15k + 6
0
Thus,
[tex]\frac{35k^{2}+29k+ 6}{5k + 2} = 7k+3[/tex]
The average cost per item is [tex]\boxed{7k+3}[/tex].
