I need to know how to calculate this

An employee works 43 hours (43 - 40 were overtime hours) during a workweek in December of 2019. He earns $42/hour, with his employer paying 1.5 times the regular rate of pay for overtime hours. To date, he has earned $132,300 during the year. He has requested that his employer withhold 6.5% of gross pay, which is to be contributed to a 403(b) plan.
