Let 1 B be 1 blue bag.
Let 1 V be 1 violet bag.
2 u = 4 B
1 u = 2 B --- (1)
1 u = 14 V --- (2)
(1) = (2)
2 B = 14 V
1 B = 14 ÷ 2 = 7 V
1 B + 2 V = 81 --- (3)
Substitute 1 B = 7 V into (3).
7 V + 2 V = 81
9 V = 81
1 V = 81 ÷ 9 = 9
From (2)
1 u = 14 V
1 u = 14 x 9 = 126
Number of candy sticks that Raeann had at first
= 2 u + 1 u
= 3 u
= 3 x 126
= 378
Answer(s): 378
