The controller of Sunland Industries has collected the following monthly expense data for use in analyzing the cost behavior of maintenance costs. Month Total Maintenance Costs Total Machine Hours January $2,590 330 February 2,890 380 March 3,490 530 April 4,390 660 May 3,090 530 June 5,470 730 (a1) Determine the variable cost components using the high-low method. (Round answer to 2 decimal places e. g. 2.25.) Variable cost per machine hour $

Variable cost per unit= $7.2 per unit

Explanation:

Giving the following information:

Month Total Maintenance Costs Total Machine Hours

January: $2,590 - 330

February: $2,890 - 380

March: $3,490 - 530

April: $4,390 -  660

May: $3,090 - 530

June: $5,470 - 730

To calculate the variable cost under the high-low method, we need to use the following formula:

Variable cost per unit= (Highest activity cost - Lowest activity cost)/ (Highest activity units - Lowest activity units)

Variable cost per unit= (5,470 - 2,590) / (730 - 330)

Variable cost per unit= $7.2 per unit

answer: marginal utility of the fourth brownie is 0.

explanation: marginal utility is the addtional utility gained from the consumption of one more unit of a good. it is given by,

so, marginal utility at the 4th unit will be given by

since, the values are not given here, you can simply find marginal utility at fourth unit by subtracting total utility at 3rd unit from total utility at 4th unit.
