Asked by edgard

John has $20 to spend at a used bookstore.
He wants to buy twice as many science fiction books as mystery books.
Mystery books sell for $1.25.
Science fiction books sell for $1.75.
Tax is included in the prices.
What is the greatest number of science fiction books that John can buy?

~How would you set up this problem?
Answered by PsyDAG
M = S/2

1.25M + 1.75S ≤ 20

Substitute S/2 for M in the second equation and solve for S.
