Morning:
From 8: 00 - 12: 00, we have 4 hours
If they pay $15/hr
Pay for 4 hours = 4 x $15 = $60
Afternoon :
From 12: 45 - 17: 30, we have 4 hours 45 minute
4hours = $60
To get the amount per minute
Simply divide $15 by 60, it will give ; $0.25 / min
so 45 min = 45 x $0.25= $11.25
4hours 45 minute = $60 + $11.25 = $71.25
Total pay for the day = $60 + $71.25 =$131.25
