Answer:
   4 oz of water must be evaporated
Step-by-step explanation:
If we let x represent the amount of water to be evaporated, the relation between the solutions is ...
   0.08 · 36 oz = 0.09 · (36 -x) oz
   0.09x = 36(0.09 -0.08) . . . . . divide by oz; add .09x, subtract .08·36
   x = 36· 0.01/0.09 = 36/9 = 4
4 ounces of water must be evaporated.
