===========================
It's not stated but implied that all pizzas cost the same. Assuming that's true:
----
d = delivery fee
p = pizza cost
------
2p + d = 25
5p + d = 58
------------------------ Subtract
-3p = -33
p = $11
2*11 + d = 25
d = $3
=================
How many pizzas are delivered to a customer who pays $80?
11p + 3 = 80
11p = 77
p = 7 pizzas
