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:

$\boxed{7k + 3}$

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.

<u> 7k + 3 </u>

5k + 2)35k² + 29k + 6

<u>35k² + 14k</u>

15k + 6

<u>15k + 6</u>

0

Thus,

$\frac{35k^{2}+29k+ 6}{5k + 2} = 7k+3$

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

Known fact:

$100 dollars for 8 hours of work --> $100 / 8hrs = $12.50 dollars/hrs

Two hours of work = $12.50 dollars/hr * 2hrs = $25 dollars

Six hours of work = $12.50 dollars/hr * 6hrs = $75

Ten hours of work = $12.50 dollars/hr * 10hrs = $125

fourteen hours of work = $12.50 dollars/hr * 14hrs = $175

Thus the answer is the bottom left choice.
