Answer
the answer is 90 (C)
Explanation:
Beth = x
Caroline = 60 + x (because if Beth has 60 less than Caroline then Caroline has 60 more than Beth)
Since the ratio = 1/3 ( another way of writing 1:3) then x/60+x = 1/3
3x = 60 + x
3x - x = 60
2x = 60
x = 60/2
x = 30 (Beth has 30 stickers)
Caroline has 60 + x stickers = 60 + 30 = 90
