Ian and Hazel had the same number of chocolate bars. After Hazel gave away 15 chocolate bars and Ian gave away 47 chocolate bars, Hazel had 3 times as many chocolate bars as Ian. How many chocolate bars did each of them have at first?
| |
Ian |
Hazel |
| Before |
1 u + 47 |
3 u + 15 |
| Change |
- 47 |
- 15 |
| After |
1 u |
3 u |
The number of chocolate bars that Ian and Hazel had at first is the same.
3 u + 15 = 1 u + 47
3 u - 1 u = 47 - 15
2 u = 32
1 u = 32 ÷ 2 = 16
Number of chocolate bars that each of them had at first
= 1 u + 47
= 16 + 47
= 63
Answer(s): 63
