Answer 1

Looks like you didn't finish because there is no question.  I'll break that problem down for you and hopefully the missing question will be answered. :) 

$11 x 40h = $440
Overtime pay and holiday pay is time and a half = $11 x 1.5 = $16.50
$16.50 x 9 hours overtime = $148.50
$16.50 x 12 hours holiday = $198.00
Holiday and OT= $346.50
Total of check including regular hours, holiday pay and overtime = $786.50
