Final answer:
The average hourly wage earned during the entire period is $2.
Step-by-step explanation:
To find the average hourly wage earned during the entire period, we need to first calculate the total wage earned. The wage starts at $7.25/hr and increases by $0.50/hr² after each hour. We can use the formula for the sum of an arithmetic series to calculate the total wage earned in 8 hours:
Total wage = (first hour wage + last hour wage) * (number of hours / 2)
Total wage = (7.25 + (7.25 + 0.50(8-1))) * (8 / 2)
Total wage = (7.25 + 12.75) * 4 = $80
The average hourly wage can then be obtained by dividing the total wage by the number of hours worked:
Average hourly wage = Total wage / Number of hours
Average hourly wage = $80 / (8 hours/day * 5 days)
Average hourly wage = $80 / 40 = $2
The average hourly wage earned during the entire period is $2.
