Abi and Vanessa had the same number of coins. After Abi had given away 62 coins, Vanessa had 3 times as many coins as Abi. How many coins did each of them have at first?
| |
Abi |
Vanessa |
| Before |
1 u + 62 |
3 u |
| Change |
- 62 |
|
| After |
1 u |
3 u |
Number of coins that Vanessa had remains unchanged.
Number of coins that Abi and Vanessa had at first is equal.
3 u = 1 u + 62
3 u - 1 u = 62
2 u = 62
1 u = 62 ÷ 2= 31
Number of coins that each of them had at first
= 1 u + 62
= 31 + 62
= 93
Answer(s): 93
