Answer: Tim worked on Monday 7:30 and earned $56.25
Step-by-step explanation: Looking at the timecard, Tim entered his job at 8:15 and left at 4:15. If we count the hours as 24h per day, 4:15 is equal 16:15, so, with that:
16:15 - 8:15 = 8h
But, Tim has a half hour lunch, then, on Monday:
8 h - 30 min = 7h30min
In other words, Tim worked 7 hours and 30 minutes on Monday.
For his earnings: He earns $7.50 per hour. As he worked 7h:
1 hour = 7.50
7 hours = 7.(7.50) = 52.50
But, Tim worked 7 hours and 30 minutes. If 1 hour is $7.50, half hour is
= 3.75
Finally, in 7 hours and 30 minutes, Tim, roughly, receives:
$52.50 + $3.75 = $56.25
On Monday, Tim received $56.25.
