Question

A person purchased 5k + 2 items for a total cost of 35k 2 + 29k + 6. Find the average cost per item of this purchase.

Answer 1

Answer:7k+3

Explanation:

Answer 2

`\boxed{7k + 3}`

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,

`(35k^(2)+29k+ 6)/(5k + 2) = 7k+3`

The average cost per item is
`\boxed{7k+3}`.
