            The given is,

                    Olivia can make 2 stone crafts in 45 minutes.

                    She has been working for 35 minutes on an order for 8 stone crafts.

Step:1

           To find the Time to make 1 stone craft

            Time for 1 stone craft = 45÷2

                                            = No. Of stone crafts × Time for 1 stone craft

                                            = 8 × 22.5

                  Remaining time to work = Total time - Already worked time

                                                           = 180 - 35

                                                           = 145 minutes.
