The multiply choice were worth 4 points. 
Gretchen= 18x+19
Ezia= 15x+31
So basically you can enter any number. At first I picked 3 and then I did the math and I got 73 points for Gretchen and 76 points for Ezia. 
Then I pick four and then I got 91 points for them both. This is how I got the answer: 
18x+19=15x+31
18(4)+19=15(4)+31
72+19=60+31
91=91
