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:

• Substitution Method
• Elimination Method
• Cramer's Method

No matter what method we use, we get the same answer:

• d = 8
• i = 5
