Answer:
$18.33 per hour
Explanation:
The Nominal wage of year 8 = $19 per hour
CPI in year 8 = $115
CPI in year 7 = $111
We can calculate wage in real term by just a simple formula
Real wage of year 8 = Nominal wage/Current year CPI x Previous year CPI
Real wage of year 8 = $19/$115 x $111
Real wage of year 8 = $18.33 per hour
