I think you meant how many roses did he buy?

If not, then the easy answer is $3 each! :)

But assuming you meant how many roses did he buy:

We must find the value for the number of daisies bought, d, which satisfies the following equation:

$27 = $1(d) + $3(d - 3)

Using the very sophisticated guess and check method we find that the answer is:

d = 9

Therefore, the number of roses bought is 6.
