$8.7205 or $8.72

Explanation:

100% $\to$ $rarr$ $8.15
100% + 7% $\to$ $rarr$ ?

$\frac{107 % \times $ 8.15}{100}$ $(107%xx$8.15)/100$ = $8.7205

$7 %$ $7%$ increase = $\frac{100 + 7}{100}$ $(100+7)/100$
$8.15 = \frac{815}{100}$ $8.15 = 815/100$
Now that his wage was $8.15, now his wage is,
$\frac{815}{100}$ $815/100$ x $\frac{107}{100}$ $107/100$
$= $ 8.7025$ $=$8.7025$
