Henry and Sam had a total of 217 stamps at first. After Henry bought 22 more stamps and Sam gave away 17 stamps, Henry now has the same number of stamps as Sam. How many stamps did Henry have at first?
| |
Henry |
Sam |
Total |
| Before |
1 u - 22 |
1 u + 17 |
217 |
| Change |
+ 22 |
- 17 |
|
| After |
1 u |
1 u |
222 |
Total number of stamps in the end
= 217 + 22 - 17
= 222
2 u = 222
1 u = 222 ÷ 2 = 111
Number of stamps that Henry had in the end
= 1 u
= 111
Number of stamps that Henry had at first
= 111 - 22
= 89
Answer(s): 89
