You are at a restaurant and your bill comes to $31.18. The sales tax is 6% and you give the waitress a 20 percent tip on the tot
Vanyuwa [196]

Answer:

$ 0.34   or 34 cents

Step-by-step explanation:

Bill amount = $31.18

sales tax = 6%  of $31.18

             =  0.06 ($31.18)

             = $1.8708

Bill with tax = $31.18+$1.8708

                  = $33.0508

value of tip = 20% of 33.0508

                   =  6.61016

Total  payment  = 33.0508+ 6.61016

                           = $39.66096

                          or $39.66

                         We get change of $40 - $39.66

                                                = $ 0.34        

We shall get back in  cents that will be 34   cents
