Pamela and Wendy had the
same number of chocolate bars at first. Pamela gave 12 chocolate bars away to her brother. In the end, Wendy had four times as many chocolate bars as Pamela. How many chocolate bars did Pamela have at first?

| Before |
4 u |

| Change |
- 12 |

| After |
1 u |
4 u |
The number of chocolate bars that Wendy had remains unchanged.
Number of chocolate bars that Pamela gave away
= 4 u - 1 u
= 3 u
3 u = 12
1 u = 12 ÷ 3 = 4
Number of chocolate bars that Pamela had at first
= 4 u
= 4 x 4
= 16
Answer(s): 16
