Answer
Find out the how many roses does she buy .
To prove
Let us assume that the number of flowers Carmen buys be x.
As given
Carmen buys 4 daisies and some roses to make a flower arrangement.
[tex]The\ number\ of\ daisies\ is\ \frac{1}{3} of\ the\ number\ of\ roses\ that\ carmen\ buys.[/tex]
Than the equation becomes
[tex]4 = \frac{x\times 1}{3}[/tex]
4 × 3 = x
12 = x
Therefore the Carmen buys number of roses be 12 .
