Ok so start with the proportion 12/2 (the number of quizzes per 2 weeks) and set it equal to 18/X (X being the number of weeks that will equal 18 quizzes) after that cross multiply to get 12X=36. divide by 12 to get X=3 weeks
Let the 2 numbers be x and y
x+ y = 35
let the larger number be x
3x = 4y
y = 3x/4
so,
x + 3x/4 = 35
7x/4 = 35
x/4 = 5
x = 4*5 = 20
so the larger number is 20.
My answer is C. So good luck!
