for 30 guests costs for dinner is $315 for each guest

so if one guest cost $315

then 30 guests costs 315×30=9450$

and for 60 guests cost for dinner is $555 for each guest

so if one guests costs $555

then 60 guests costs 555×60=33300$

cost for 90 guests = cost for 30 guest + cost for 60 guests

                                = 9450+33300 = 42750$
