First, let's find the 7.25% tax by multiplying each price by 7.25% in its decimal form:
[tex]\begin{gathered} (8.00)(0.0725)=0.58 \\ (22.00)(0.0725)=1.6 \\ (14.50)(0.0725)=1.05 \end{gathered}[/tex]Next, to calculate the price including tax, we have to add the sales tax with the price before tax to get the following:
[tex]\begin{gathered} 8.00+0.58=8.58 \\ 22.00+1.60=23.60 \\ 14.50+1.05=15.55 \end{gathered}[/tex]
