Mary and Eva had the
same number of candy canes at first. Mary gave 15 candy canes away to her sibling. In the end, Eva had four times as many candy canes as Mary. How many candy canes did Mary have at first?

| After |
1 u |
4 u |
The number of candy canes that Eva had remains unchanged.
Number of candy canes that Mary gave away
= 4 u - 1 u
= 3 u
3 u = 15
1 u = 15 ÷ 3 = 5
Number of candy canes that Mary had at first
= 4 u
= 4 x 5
= 20
Answer(s): 20
