Ms. Franklin, the head librarian at the Harrison County Library, can spend at most $3,500 to expand the children's section of the library. When she buys from a particular discount seller, paperback books cost $4 each and hardback books cost $8 each.
Write the inequality in standard form that describes this situation. Use the given numbers and the following variables.
x = the number of paperback books
y = the number of hardback books
The cost of purchasing paperback books is $4x and the cost of purchasing hardback books is $8y. Since Ms. Franklin can spend at most $3,500, the inequality can be written as:
4x + 8y ≤ 3500
