Ed and Ann both have smoothies with their lunch. Ed orders the regular size. Ann gets the large smoothie, which is $50\%$ more than the regular. After both consume $\frac{1}{2}$ of their drinks, Ann gives Ed a quarter of what she has left, and $3$ additional ounces. When they finish their smoothies they realize that they both drank the same amount. How many ounces of smoothie did they drink together?
