Question

you have five friends and go to lunch. You plan to split the bill evenly, and you plan to leave a 15% tip. The bill is $55.50 before the tip. Which is the closest to the amount each person will pay for the meal, including tax?

Answer 1

The closest to the amount each person will pay for the meal including the tax is $10.64

Firstly, we will need to calculate the total bill including the tip

Mathematically, this will be;

$\begin{gathered} 55.50\text{ + 15\% of \ 55.50} \\ We\text{ have;} \\ \\ 55.50\text{ + (}\frac{15}{100}\text{ }\times\text{ 55.50)} \\ \\ =\text{ 55.50 + 8.325 = \ 63.825} \end{gathered}$

So the amount that each will pay will be the division of the total amount including the tip by the total number of persons which is 6 in this case (you plus 5 friends)

So the individual bill will be;

$\begin{gathered} \frac{63.825}{6}\text{ = \ 10.6375} \\ \\ \text{This is closest to \ 10.64} \end{gathered}$
