    Alberto and Willie each improved their yards by planting daylilies and ivy. They bought their supplies from the same store. Alberto spent $64 on 3 daylilies and 8 pots of ivy. Willie spent $107 on 9 daylilies and 7 pots of ivy. What is the cost of one daylily and the cost of one pot of ivy?

    Assumptions:
    • Let d be the cost of one daylily
    • Let i be the cost of one pot of ivy
    Givens:
    1. 3d + 8i = 64
    2. 9d + 7i = 107
    To solve this system of equations, you can use any of three methods below:
    No matter what method we use, we get the same answer:
    • d = 8
    • i = 5
