The school is selling potted plants as a fundraiser. Kara sold 12 ferns and 8 ivy plants for $260. Paul sold 15 ivy plants and 6 ferns for $240. what is the selling price of each plant?

x=ferns; y=ivy

12x+8y=260

6x+15y=240

x=60 - (15/6) y

12 (60 + (15/6) y + 8y = 260

x=60 - (15/6) y

720 - 30y + 8y = 260

x=60 - (15/6) y

-30y + 8y = 260-720 = => - 22y = - 460

x=60 - (15/6) y

y = (-460) / (-22) = 20.9090909091

y=20.90

x=60 - (15/6) * 20.90 = 7.75

* (ferns) = 7.75$

y (ivy) = 20.90$
