Chad and Amy are married with no children, and they're filing their federal
income tax return. Chad had a gross income of $54,300 last year, while Amy had
a gross income of $50,900; they plan to use the standard deduction. They're
trying to decide whether to file their return jointly or separately, so they want to
calculate how much less they would pay in federal income taxes if they filed
jointly rather than separately.

Part 3: When filing jointly, Chad and Amy have a standard deduction of $11,400, they can claim one exemption for each of them for $3650 each, and they don’t have any addition adjustments to income. What is their taxable income?
