Answer:
rose$7  shrub $11
Step-by-step explanation:
5r+3s=68
1r+14s=161
I will multiply the second by -5 to eliminate r variable
5r+  3s= 68
-5r- 70s = -805
         -67s  = -737
             Divide both by -67
           s= 11
14*11=154
161-154 =7
       5*7 + 3*11 = 68
     35+33 = 68
        7+ 14*11 = 161
7+154 = 161
