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$
