Question

Suppose a family dinner costs $94.25 and we want to leave a 16% tip. If sales tax is 6%, what is the total including tax and tip? Round to the nearest cent.

Answer 1

$ 115.0

Explanation:

To calculate the total value, we must add the cost of the dinner, plus the value corresponding to the tax and the tip, just like this:

`\begin{gathered} T=\text{dinner + tax + tip} \\ \text{dinner = 94.25} \\ \text{tax = 94.25}\cdot(6)/(100)\text{ = }5.655 \\ \text{tip = 94.25}\cdot(16)/(100)=15.08 \\ \text{replacing:} \\ T=94.25+5.655+15.08 \\ \text{Total = }114.985\text{ }\cong115.0 \end{gathered}`

Total value is $ 115.0
