Let 鈥榣鈥� represents the number of lilies, 鈥榬鈥� represents the number of roses and 鈥榙鈥� represents the number of daisies.

The sum of number of flowers should be equal to.$24$

The equations are,

$\begin{array}{c}l+r+d=24\text{鈥夆赌夆赌夆赌夆赌夆赌夆赌夆赌夆赌夆赌夆赌夆赌夆赌夆赌夆赌夆赌夆赌夆赌夆赌夆赌�}\mathrm{......}\left(1\right)\\ 3l+2r+0.5d=24\text{鈥夆赌夆赌夆赌夆赌夆赌�}\mathrm{......}\left(2\right)\end{array}$

Perform the operation on equations, $3脳\left(1\right)鈭�\left(2\right)$

$\begin{array}{l}3l+3r+3d=72\\ 3l+2r+0.5d=24\\ 鈭�鈭�鈭�鈭�鈭�鈭�鈭�鈭�鈭�鈭�鈭�\\ r=48鈭�2.5d\text{鈥夆赌夆赌夆赌夆赌夆赌夆�夆赌夆赌夆赌夆赌夆赌夆�夆赌夆赌夆赌夆赌夆赌夆��}\mathrm{......}\left(3\right)\end{array}$

Perform the operation on equations,$2脳\left(1\right)鈭�\left(2\right)$ .

$\begin{array}{l}2l+2r+2d=48\\ 3l+2r+0.5d=24\\ 鈭�鈭�鈭�鈭�鈭�鈭�鈭�鈭�鈭�鈭�鈭�\\ l=鈭�24+1.5d\text{鈥夆赌夆赌夆赌夆赌夆赌夆�夆赌夆赌夆赌夆赌夆赌夆�夆赌夆赌夆赌夆赌夆赌夆��}\mathrm{......}\left(4\right)\end{array}$

Choose the value of 鈥榙鈥� such that the values of 鈥榣鈥� and 鈥榬鈥� are positive.

Using trial and error method, the value should be, $d=18$

Substitute this value in the equations (3) and (4)

$\begin{array}{c}r=48鈭�2.5\left(18\right)\\ 鈭�r=3\end{array}$

$\begin{array}{l}l=鈭�24+1.5\left(18\right)\\ 鈭�l=3\end{array}$

Verification:

The number of lilies, roses and daisies are,$l=3,r=3,d=18$ .

Hence, Kyle would buy a bouquet of $\$24$consisting of $3$lilies, $3$roses and $18$daisies.
