The school is selling potted plants as a fundraiser. Kara sold 12 ferns and 8 ivy plants for 260.00. Paul sold 15 ivy plants and 6 ferns for 240. What’s the selling price of each plant.

Let the cost of each fern be f
Let the cost of each ivy plant be I

We're given:

1. 12f + 8i = 260
2. 15i + 6f = 240

To solve this system of equations, we can use 3 methods:

• Substitution Method
• Elimination Method
• Cramer's Rule

No matter which method we choose, we get the same answer:

• f = 7.5
• i= 21.25
