Georgia uses the high-low method of estimating costs. Georgia had total costs of $50,000 at its lowest level of activity, when 5,000 units were sold. When, at its highest level of activity, sales equaled 12,000 units, total costs were $78,000. Georgia would estimate variable cost per unit as

a. $6.50

b. $10.00

c. $4.00

d. $7.53

Variable cost per unit= $4

Explanation:

Giving the following information:

Georgia had total costs of $50,000 at its lowest level of activity when 5,000 units were sold. When, at its highest level of activity, sales equaled 12,000 units, total costs were $78,000.

Using the high-low method, we need to use the following formula to determine the unitary variable cost:

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

Variable cost per unit= (78,000 - 50,000) / (12,000 - 5,000)

Variable cost per unit= $4

the assumption the narrator makes in this excerpt is that the messages he heards were going to hurt the narrator's mom; the narrator just springs in to action. the narrator doesn't specify in this excerpt why he believes that the messages present a problem that requires protection.

rational decision making is a multi-step process for making choices between alternatives. the process of rational decision making favors logic, objectivity, and analysis over subjectivity and insight. the word “rational” in this context does not mean sane or clear-headed as it does in the colloquial sense.
