Answer:
Step-by-step explanation:
Let’s use the tax rate schedule for 2019
Since Chuck status is single and earned $80,750.
He would pay 10 percent on the first $9,700 of his earnings ($970);
Then 12 percent on the other earnings from $9,701 to $39,475 ($3,573); and then 22 percent on the remaining income, up to $80,750 ($9,081).
Chuck total tax bill would be $13,624. Divide that by adding his earnings of $80,750 and interest of $30,750 and you get an effective tax rate of 12.22 percent.
