Answer:
His regular earnings ( based on regular rates) is $480 while his total earnings for the week ended March 15 is $738.
Explanation:
Regular rate = $12 per hour
Rate for hours in excess of 40 hours per week
= (3/2) × $12
= $18
Rate for hours for Sunday is double
= 2 × $12
= $24
During the week ended March 15, 9 hours each day from Monday through Friday, 6 hours on Saturday, and 4 hours on Sunday
Period in excess of 40 hours during the week
= (9 × 5) + 4 - 40
= 9
Total regular earning = 40 × $12
= $480
Additional earnings = (9 × $18) + (4 × $24)
= $162 + $96
= $258
Total earnings = $480 + $258
= $738
