Linda and Kylie had the same number of coins. After Linda had given away 69 coins, Kylie had 4 times as many coins as Linda. How many coins did each of them have at first?
| |
Linda |
Kylie |
| Before |
1 u + 69 |
4 u |
| Change |
- 69 |
|
| After |
1 u |
4 u |
Number of coins that Kylie had remains unchanged.
Number of coins that Linda and Kylie had at first is equal.
4 u = 1 u + 69
4 u - 1 u = 69
3 u = 69
1 u = 69 ÷ 3= 23
Number of coins that each of them had at first
= 1 u + 69
= 23 + 69
= 92
Answer(s): 92
