Ava wants to make a bracelet using green and brown crystal beads. The green beads costs $3 each, and the brown beads costs $8 each. Ava has at most $32 to spend on the project. Ava also wants to control the dominant color of the bracelet, so she requires the number of brown beads to be less than four times the number of green beads. a) Write a system of linear inequalities that represents the combinations of the number of green and brown beads that satisfies Ava's requirements. Let x be the number of green beads, and y be the number of brown beads.
