Given :

a restaurant customer left a $1.95 as a tip.

The tax = 5%

the tip was 15% of the after-tax cost

So, the information that not needed is the tax

Let the total bill = x

so, 15% of x = 1.95

\begin{gathered} 0.15\cdot x=1.95 \\  \\ x=\frac{1.95}{0.15}=13 \end{gathered}

so, the total bill = $13
