2. You have $60 to buy fi sh for a 30-gallon aquarium. Each angelfi sh costs $12
and needs at least 6 gallons of water. Each neon tetra costs $3 and needs at
least 3 gallons of water. How many of each kind of fi sh can you buy?
Let x 5 the number of angelfi sh,
and y 5 the number of neon tetras.
Cost: 12x 1 3y # 60
y # 24x 1 20
Water: 6x 1 3y # 30
y # 22x 1 10
Th e solution is represented by points in the shaded area with
integral coordinates.
