what the expression represents.​

Answer:

The expression represents the total cost of the bag which contain x number of goby and x number of shrimp.

Step-by-step explanation:

Each goby fish costs $15 and each shrimp costs $10.

Each bag has an equal number of goby fish and shrimp.

So. let each bag has x number of goby and x number of shrimp

so, the cost of the bag = 15x + 10x

Take x as a common

so, the total cost = x (15+ 10)

so, the expression represents the total cost of the bag which contain x number of goby and x number of shrimp.

Step-by-step explanation:

a.Possible answer: The expression (15 1 10) shows the cost of one fish and the cost of one shrimp. The variable x represents the number of fish and the number of shrimp in each bag. The sum of the two costs is multiplied by the number of fish and shrimp in each bag.
