To determine the total charge we first need to calculate how much we pay of taxes. This can be done by using a rule of three:
[tex]\begin{gathered} 47.5\rightarrow100 \\ x\rightarrow8 \end{gathered}[/tex]Then we have:
[tex]x=\frac{8\cdot47.5}{100}=3.8[/tex]Hence charge for the tax is $3.8.
Therefore the total charge of the meal is $51.3
