Graphs of Linear Inequalities · Exercise 50

Shopping. Tula has $20 to spend at the used book sale. Hardcover books cost $2 each and paperback books cost $0.50 each. If x is the number of hardcover books Tula can buy and y is the number of paperback books she can buy, the inequality $2 x + \frac{1}{2} y \leq 20$ models the situation.

ⓐ Graph the inequality.
ⓑ List three solutions to the inequality $2 x + \frac{1}{2} y \leq 20$ where both x and y are whole numbers.
