◻ A. The cost of 4 tetras is the same as the cost of a rainbow fish.
◻ B. One rainbow fish plus 5 tetras cost $21.
◻ C. An equation to find the cost r, in dollars, of a rainbow fish is 8r + 2(r + 6) = 37
◻ D. Reducing the number of rainbow fish by 1 would result in a total cost of $28.50.
◻ E. An equation to find the cost t, in dollars, of a tetra t is 8t + 2t + 6 = 37.
