Question

if their original bill is $15.50 what will be the final bill after paying a 15% tip round to the nearest cent

Answer 1

we have:

$15.50 -----> 100%

x --------------> 15%

then

`\begin{gathered} x*100=15.50*15 \\ x=15.50*(15)/(100) \\ x=15.50*0.15 \\ x=2.325 \end{gathered}`

so,

`15.50+2.325=17.83`

answer: $ 17.83 is the final bill
