Part I

The weight of the truck without cargo is 22150+11300= 33450 pound
The weight of the cargo is given as c and altogether with the weight of the truck, the sum must not exceed 75500

The inequality is given 33450+c \leq 75500

Part II
33450+c \leq 75500
c \leq 75500-33450
c \leq 42050

Hence, the maximum weight allowed for the cargo is 42050 pounds
