<h3>Data and Calculations:</h3>
Gross earnings in 1990 = $48,000
Maximum taxable income in 1990 = $17,700
Social Security Tax Rate = 6.5%
Gross monthly pay = $4,000 ($48,000/12)
Monthly Social Security Tax = $260 ($4,000 x 6.5%)
Total Social Security Tax = $1,150.50 ($17,700 x 6.5%)
In 5 months, Dawn would have paid a <em>total of $1,150.50</em> ($260 x 4 + $110.50) in Social Security Tax.
Thus, the total Social Security Tax paid by Dawn in that year was <em>$1,150.50.</em>
