this is a practice question I am trying to figure out how to calculate:

Barbara is an employee of Baltimore Company. Baltimore Company pays employees the Friday after the wages are earned. Overtime in excess of 40 hours must be paid at 150% of the normal hourly rate.Social Security taxes are 6.2% and Medicare taxes are 1.45%. The federal unemployment tax rate is 1.2% and the state unemployment tax rate is 4.5%. Barbara's wages, including the current pay period, will not exceed the limits for Social Security, Medicare and unemployment taxes.Barbara earns $20 per hour and worked 45 hours for the week ended January 13 , 2019.Baltimore will withhold $220 federal income taxes. determine the total payroll tax expense for Baltimore Company as related to Barbara's earnings.
