Question and answer:

Samuel Worthy earns both $7.25/hour and a 10% commission on all sales. During the most recent week, he worked 42 hours and made total sales of $11,000.

Regular Wages	$7.25 * 42 hours = $304.50
Commissions	$11,000.00 * 10% = $1,100.00
Regular Wage Rate	($304.50 + $1,100.00) / 42 hours = $33.44
Overtime Wage Rate	$33.44 * 1.5 = $50.16
Additional Overtime Wage Rate	$50.16 - $33.44 = $16.72
Additional Overtime Wages	$16.72 * (42 - 40) = $33.44
Gross Pay	$330.40 + $1,100.00 + $33.44 = $1,437.94

But using the same math, I can't figure these out.

1. Billy Fortuna earns both $11.45/hour and a 10% commission on all sales. During the most recent week, he worked 47 hours and made total sales of $8,800

2. Richard Eisenhower earns both $16.70/hour and a 12% commission on all sales. During the most recent week, he worked 46 hours and made total sales of $6,300
