First find the cost of the wire in cents per inch 

When you see "per" in a proposition it always means divide                    60 ¢ 

                                                                                                                ––––  =  4 ¢/in  

                                                                                                                15 in  

 

Now multiply the cost in ¢/in times 47 in                                                   4 ¢/n • 47 in  =  188 ¢  or  $1.88
