Erkkila Inc. reports that at an activity level of 6,800 machine-hours in a month, its total variable inspection cost is $426,530 and its total fixed inspection cost is $197,309.

What would be the average fixed inspection cost per unit at an activity level of 7,100 machine-hours in a month? Assume that this level of activity is within the relevant range.

Younger Corporation reports that at an activity level of 4,400 units, its total variable cost is $283,096 and its total fixed cost is $136,710.

For the activity level of 4,500 units, compute: (a) the total variable cost; (b) the total fixed cost; (c) the total cost; (d) the average variable cost per unit; (e) the average fixed cost per unit; and (f) the average total cost per unit. Assume that this activity level is within the relevant range. (Round your "Average cost" to 2 decimal places and other answers to the nearest dollar amount.)

a	Total Variable Cost
b	Total fixed cost
c	Total Cost
d	Average Variable Cost		per unit
e	Average fixed cost		per unit
f	Average total cost		per unit
