NO,
in working 40 hrs x $9.20 he earned $ 368.00
overtime pay is $9.20+$ 4.60= $ 13.80 per hour
$13,80 x 2.25 hours=$31.05
$368+ $31.05= $399.05
which is less than $400
He worked 42.25 hours. For the first 40 hours, he got $9.20 each hour. 40 hours times $9.20 = $368.
So how much did he get paid for the other 2.25 hours? He is paid 1.5 times $9.20 each hour after that. That's $13.80 an hour. Times two hours is $27.60.
27.6 + 368 = Only $395.60! Even if he got paid for that quarter of an hour, a quarter of $13.80 is only $3.45, which puts him at $399.05--still not more than $400.
