From the information given,we have Let p=pink roses,r=red roses,y=yellow roses So, 0.5p+10r+50y=1000.......1 p+r+y=100......2 Multiplying 10 on both sides of eq.2 10p+10r+10y=1000...3 Now subtracting eq.1from eq.3,,we have,, 9.5p-40y=0 p/y=40/9.5 p/y=400/95 p/y=80/19 Therefore pink roses =80 Yellow roses =19 Red roses=100-(80+19)=1 Thus,red roses =1
