Question

Explain how mental math can be used to estimate a 15% tip on a taxi ride that costs $23.25. Find the tip using that method.

Answer 1

Tip on a taxi ride is $3.487

Step-by-step explanation:

Here we have to find 15% of $23.25

We will first find 10% of $23.25 ,from it then we can later find 5% of it.

Here 10% of $23.25 = $2.325

        5% of $23.25 = $1.162

15% of $23.25 = 10% of $23.25 + 5% of $23.25

                                    =  $2.325 + $1.162

                                    = $3.487

So,Tip on a taxi ride is $3.487.
