A person purchased 5k + 2 items for a total cost of 35k2 + 29k + 6. The average cost per item was ___.
- A 6k + 2
- B 6k + 3
- C 7k + 2
- D 7k + 3
That's Correct!
It's Wrong!
The person purchased 5k + 2 items for a total cost of 35k2 + 29k + 6. To find the average cost per item, we divide the total cost by the number of items. Therefore, the average cost per item is (35k2 + 29k + 6)/(5k + 2). Simplifying this expression, we get 7k + 3.
