A used-book store sells paperbacks for $2 and hardcovers for $5, including tax. Amanda wants to buy at least 6 books but only has $20. She uses the system
to find the number of each type of book she should buy, where x is the number of paperbacks and y is the number of hardcovers, and shows the solution in the
graph.
2x + 5y < 20
12 +y > 6
Explain the error in Amanda's solution.
