In order to calculate the new wage per hour, first let's calculate the increase by multiplying 4% (that is, 4/100) and 13.49:
[tex]\frac{4}{100}\cdot13.49=\frac{53.96}{100}=0.54[/tex]Now, let's add this value to the old wage per hour:
[tex]13.49+0.54=14.03[/tex]Therefore the new wage per hour is $14.03.
