Suppose you intend to spend no more than $60 buying books. Hardback books cost $12 and paperbacks cost $5. How many books of each type can you buy?

Answer 1

The inequality is
12H+5P ≤ 60
Many answers are possible, such as:
H=5, P=0, total=60
H=4, P=2, total=58
H=3, P=4, total=56
H=2, P=7, total=59
