Sam and Neave had a total of 215 coins at first. After Sam bought 24 more coins and Neave gave away 15 coins, Sam now has the same number of coins as Neave. How many coins did Sam have at first?
| |
Sam |
Neave |
Total |
| Before |
1 u - 24 |
1 u + 15 |
215 |
| Change |
+ 24 |
- 15 |
|
| After |
1 u |
1 u |
224 |
Total number of coins in the end
= 215 + 24 - 15
= 224
2 u = 224
1 u = 224 ÷ 2 = 112
Number of coins that Sam had in the end
= 1 u
= 112
Number of coins that Sam had at first
= 112 - 24
= 88
Answer(s): 88
