Based on the maintenance expenses of a company are to be analyzed for purposes of constructing a flexible budget. Examination of past records disclosed the following costs and volume measures:

    Highest   Lowest
Cost per month   $86,000   $74,000
Machine hours   96,000   66,000

Using the high-low-point method of analysis, the estimated variable cost per machine hour is:
      
$0.40
      
$0.20
      
$0.90
      
$0.10
      
$0.70

Explanation / Answer

Q1. Answer is 0 adn 1

Explanation: Coefiicient of determination is square of coreelation coefficient (which lies between -1 adn +1)

Q2. Answer is $0.40

Explanation:

Variable cost per machine hours: Chnage in cost / Change in Hours = ($86,000 -74,000) /(96,000-66,000 hours) : $ 0.40 per machine hour
