Harry and Meg have some roses. 3/10 of the flowers are red roses, the rest are white roses. Harry gives 50% of the white roses away and buys 17 more red roses. They now have 121 roses in total. How many roses did they have at the start?

160.

final total is 121 after adding 17 roses so after giving away half white total is 104

initial mix is 3/10 red and 7/10 white after giving away half white total us 6.5/10 or 13/20

Divide 104 by 13/20 104/13*20=8*20=160

3/10X + 17 + 7/10X - 7/20X = 121

X = 160

160 (3/7) = 48 red

160 (7/10) = 112 white
