Answer
Explanation:
Step1: Calculate number of manual errors
The number of manually - filed tax returns is 2.7 million = 2700000. The error rate for manual filing is 20% or 0.2. So the number of erroneous manually - filed returns is $2700000\times0.2 = 540000$.
Step2: Calculate number of electronic errors
The number of electronically - filed tax returns is 2.7 million = 2700000. The error rate for electronic filing is 0.05% or 0.0005. So the number of erroneous electronically - filed returns is $2700000\times0.0005=1350$.
Step3: Calculate the difference
Subtract the number of electronic errors from the number of manual errors: $540000 - 1350=538650$.
