Answer:
$1,100
Step-by-step explanation:
The amount which Rachel must include in her 2018 gross income would be computed by applying an equation which is shown below:
= Itemized deductions - standard deductions
= $6,900 - $5,800
= $1,100
The $1,100 would be included in the $1,900 refund which is presented in her 2018 gross income.
The excess amount between itemized deductions and standard deductions would indicate the extra refund amount which is already included in its $1,900 refund amount
