The number of roses, sunflowers and tulips a florist has are in the ratio 5:6:9
after the Florist sells 50 roses, the ratio becomes 3:4:6
Find the number of roses left after 50 of them are sold
so we can conform the "after" ratio to fit the amount in the first ratio.
Since we know that T(tulips)1=T2, and S(sunflowers)1 = S2, we find that the ratio of S and T from the first ratio, determined by 9/6 and 6/4, is 1.5. We take the ratio of roses and multiply it by 1.5,and we get 4.5. therefore, 50 roses is 10% of the total. we divide 4.5 by 0.5, getting 9, and multiply that by 50.
the answer is 450 roses.
