In her backyard, Florry grows only yellow roses and white roses. Some of the rose bushes have flowers of both colors, and some have flowers of one color only. The number of rose bushes that have only yellow roses is 50% greater than the number of rose bushes that have only white roses. If there are yellow roses on 80% of Florry's rose bushes, then what percent F of her bushes have only yellow roses? Choose one
A) 20  B) 30  C) 50  D) 70  E) 80
let, the number of bushes with only yellow flowers be x   so, number of bushes with only yellow flowers will be 1.5x   if total number of bushes of flowers= T   then total number of bushes with yellow flowers= 0.8T   we can say that total number of bushes with yellow flowers+ bushes with only white flowers= total number of bushes with flowers   so, F=0.8T+x=T   x=0.2T   so, 1.5x=0.3T   30% flowers are yellow flowers   OA 30
