Answer and Explanation:
The computation of the estimated total cost & the cost per unit is given below:
For 76 units & 52 units
For EZRecords
Total cost = Fixed cost + variable cost
where
Fixed cost = $15,990 × 29 hours ÷ 39 hours
= $11,890
And, the variable cost is
= 76 units × $105
= $7,980
So, the total cost is
= $11,890 + $7,980
= $19,870
And, the cost per unit is
= $19,870 ÷ 76 units
= $261.45
For Pro office
Total cost = Fixed cost + variable cost
where
Fixed cost = $15,990 × 10 hours ÷ 39 hours
= $4,100
And, the variable cost is
= 53 units × $184
= $9,752
So, the total cost is
= $4,100 + $9,752
= $13,852
And, the cost per unit is
= $13,850 ÷ 53 units
= $261.35
For 200 units & 99 units
For EZRecords
Total cost = Fixed cost + variable cost
where
Fixed cost = $15,990 × 29 hours ÷ 39 hours
= $11,890
And, the variable cost is
= 200 units × $105
= $21,000
So, the total cost is
= $11,890 + $21,000
= $31,890
And, the cost per unit is
= $31,890 ÷ 200 units
= $159.45
For Pro office
Total cost = Fixed cost + variable cost
where
Fixed cost = $15,990 × 10 hours ÷ 39 hours
= $4,100
And, the variable cost is
= 99 units × $184
= $18,216
So, the total cost is
= $4,100 + $18,216
= $22,316
And, the cost per unit is
= $22,316 ÷ 99 units
= $225.41
