Answer:
Total cost= $650,857
Explanation:
Giving the following information:
At an activity level of 6,900 units in a month, Zeus Corporation's total variable maintenance and repair cost is $408,756, and its total fixed maintenance and repair cost is $230,253.
<u>We need to calculate the total cost of 7,100 units. Because it is between the relevant range, fixed costs will remain the same. We need to determine the unitary variable cost.</u>
Unitary variable cost= total variable cost/ unit
Unitary variable cost= 408,756/6,900= $59.24
Total cost= 59.24*7,100 + 230,253= $650,857
