This one was a little confusing!

Payroll data for the current week are as follows: hours worked, 48; federal income tax withheld, $950; Social security tax rate, 6.0%; and Medicare tax rate, 1.5%; state unemployment compensation tax, 5.4% on the first $7,000; federal unemployment compensation tax, 0.8% on the first $7,000. Calculate the employer's payroll tax expense under the following circumstances. Round your answers to two decimal places. a. This is the first payroll of the year and the employee has no cumulative earnings for the year to date. $ b. The employee's cumulative earnings for the year prior to this week equal $6,200. $
