Work Step by Step
(a)
The calculation of gross income is mentioned below-
\[\begin{align}
& \text{Gross income}=\text{Wages}+\text{Earned interest} \\
& =\$46,500+\$790\\&=\$47,290\end{align}\]
Hence, the amount of gross income is\[\$47,290\].
(b)
The calculation of adjusted gross income is mentioned below-
\[\begin{align}
& \text{Adjusted gross income}=\text{Gross income}-\text{Adjustments} \\
& =\$47,290-\$1,100\\&=\$46,190\end{align}\]
Hence, the amount of adjusted gross income is\[\$46,190\].
