To find the average amount that Kevin earns per hour during a day, we need to calculate the total earnings and divide it by the total number of hours worked.

First, let's calculate Kevin's earnings for his regular 8 hours of work:

Regular earnings = Hourly rate * Hours worked
Regular earnings = $15/hour * 8 hours
Regular earnings = $120

Next, let's calculate Kevin's earnings for his overtime hours:

Overtime earnings = Hourly rate * Hours worked
Overtime earnings = $18/hour * 4 hours
Overtime earnings = $72

Now, we can calculate the total earnings:

Total earnings = Regular earnings + Overtime earnings
Total earnings = $120 + $72
Total earnings = $192

Finally, let's calculate the average earnings per hour:

Average earnings per hour = Total earnings / Total hours worked

The total hours worked are the regular hours (8) plus the overtime hours (4):

Total hours worked = Regular hours + Overtime hours
Total hours worked = 8 hours + 4 hours
Total hours worked = 12 hours

Substituting the values into the formula:

Average earnings per hour = $192 / 12 hours
Average earnings per hour = $16

Therefore, the average amount that Kevin earns per hour during a day is $16.
