To date, jay ward has a cumulative earnings of $95,000. this week he is paid $3,000. the total amount of social security tax for this week is: (assume a rate of 6.2% on $97,500 for social security and 1.45% for medicare).

The question I have is do you include what the employer would pay as well as what the employee would pay?  If not, the Social Security Tax would be $155.  If so, it would be double, or $310.
$97,500 Social Security base-95,000 Cumulative Earnings=2,500
$2,500 * 6.2% (0.62) = $155
