Answer:

6 hours

Explanation:

Let k = time it takes Karen to paint the house alone

then  according to the question,

(2/3)(k)(1/k + 1/12) = 1

⇒(2k/3)(1/k + 1/12) = 1

⇒(2k)(1/k + 1/12) = 3

⇒(2 + k/6) = 3

Multiplying both sides by 6:

12 + k = 18

k = 6 hours

therefore Karen takes 6 hours to complete the Task.

Endor Company begins the year with $110,000 of goods in inventory. At year-end, the amount in inventory has increased to $118,00
Arada [10]

Answer:

11.40

32 days

Explanation:

Inventory turnover and days of sales of inventory are examples of activity ratios.

They are used to measure the efficiency of performing daily tasks

inventory turnover =  Cost of goods sold/ average inventory

Average inventory = ($118,000 + $110,000) / 2 = $114,000

Inventory turnover =  $1,300,000 / $114,000 = 11.40

days of sales of inventory = 365 / inventory turnover = 365 / 11.40 = 32 days
