Sidney Darling is a telemarketer, who is paid $0.34 for every telemarketing call he places. During the most recent week, he worked 41 hours and placed 1,642 calls.

Regular Earnings for all Hours	$0.34 * 1,642 units = $558.28
Regular Wage Rate	$558.28 / 41 hours = $13.62
Additional Overtime Hourly Rate	$13.62 * 0.5 = $6.81
Additional Overtime Earnings	$6.81 * (41 - 40) = $6.81
Gross Pay	$558.28 + $6.81 = $565.09
