Bobby and Tina had the same number of chocolate bars. After Tina gave away 21 chocolate bars and Bobby gave away 46 chocolate bars, Tina had 6 times as many chocolate bars as Bobby. How many chocolate bars did each of them have at first?
| |
Bobby |
Tina |
| Before |
1 u + 46 |
6 u + 21 |
| Change |
- 46 |
- 21 |
| After |
1 u |
6 u |
The number of chocolate bars that Bobby and Tina had at first is the same.
6 u + 21 = 1 u + 46
6 u - 1 u = 46 - 21
5 u = 25
1 u = 25 ÷ 5 = 5
Number of chocolate bars that each of them had at first
= 1 u + 46
= 5 + 46
= 51
Answer(s): 51
