Question 1038399
You posted the problem twice that I saw, and both times you left out one piece of information:
"twice as many liked all 3, liked only ice cream and almond"
QK, I get it, twice as many refers to 9 so this number is 18 liked all 3. But then you say ",liked only ice cream and almond" How many liked only ice cream and almond? Is this in addition to the "9 liked ice cream and almonds"?
