Step-by-step explanation:

$Ben\ invited\ p\ peoples\\\\$

Charges of birthday party:

$Flat\ fees=\$ 45\\\\Per\ person\ charges=\$ 5.50\\\\Charges\ for\ p\ people=p\times per\ person\ charges\\\\Charges\ for\ p\ people=p\times 5.50\\\\Charges\ for\ p\ people=5.50p\\\\Total\ charges\ for\ party=flat\ fee+charges\ for\ p\ person\\\\Total\ charges\ for\ party=45+5.50p$
