Lane is buying fish for his aquarium. Tetras cost $5 each and cichlids cost $19 each. Lane would like to have at least 8 fish in all, but he can spend no more than $100 give a reasonable solution

Buy 4 of Tetra fish and 4 Cichlids

Step-by-step explanation:

First you can figure out that if u buy 8 of the tetras, you will have 60 left. Then finding the difference of price between the fishes, you get 14. Then dividing 14 by 60, you get 4.28. This means you can replace 4 of your Tetras with Cichlids. Therefore you will spend 96, having 4 left
