Each bag has an equal number of goby fish and shrimp. A.The pet store models the cost per bag with the expression x(15 1 10). Explain what the expression represents. B. What other expression can you use to model the cost? Explain what the expression represents.

a) Interpretation of the expression

b)                

Step-by-step explanation:

We are given the following in the question:

Unit cost of goby fish = $15

Unit cost of shrimp = $10

There are equal number of goby fish and shrimp in a bag.

A) The cost per bag with the expression

B) Expression for total cost

where C(x)  is the total cost and x is the number of goby fish or the number of shrimps that are equal.

46.2+112.3

step-by-step explanation:

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4
