Seth and George had a total of 212 erasers at first. After Seth bought 28 more erasers and George gave away 16 erasers, Seth now has the same number of erasers as George. How many erasers did Seth have at first?
|
Seth |
George |
Total |
Before |
1 u - 28 |
1 u + 16 |
212 |
Change |
+ 28 |
- 16 |
|
After |
1 u |
1 u |
224 |
Total number of erasers in the end
= 212 + 28 - 16
= 224
2 u = 224
1 u = 224 ÷ 2 = 112
Number of erasers that Seth had in the end
= 1 u
= 112
Number of erasers that Seth had at first
= 112 - 28
= 84
Answer(s): 84
