Problem Statement

The school store is running out of supplies, but it still has five items: one pencil (costing $1\$1), one pen (costing $1\$1), one folder (costing $2\$2), one pack of paper (costing $3\$3), and one binder (costing $4\$4). If you have $10\$10, in how many ways can you spend your money? (You don't have to spend all of your money, or any of it.)
