Answer:
5.25%
Step-by-step explanation:
The computation of the average accounting return is shown below:
Average accounting return is
= Average net income ÷ average initial cost
where,
Average net income is
= ($1,200 + $2,300 + $2,800) ÷ 3 years
= $2,100
And, the average initial cost is
= $80,000 ÷ 2
= $40,000
So , the average accounting return is
= $2,100 ÷ $40,000
= 5.25%
Hence, the average accounting return is 5.25%
