Answer:
$44,928,000
Explanation:
The fact that 416,000 received a refund of $3,600 each means that the tax authority would lose the interest income that could have been generated on the total refund amount based on a 3% interest rate of return.
Lost annual income=number of people who got refund*average refund per person*interest rate of return
number of people who got refund=416000
average refund per person=$3,600
the interest rate of return=3%
Lost annual income=416,000*$3,600*3%
Lost annual income=$44,928,000
