Ryan and Caden had a total of 167 stamps at first. After Ryan bought 20 more stamps and Caden gave away 13 stamps, Ryan now has the same number of stamps as Caden. How many stamps did Ryan have at first?
| |
Ryan |
Caden |
Total |
| Before |
1 u - 20 |
1 u + 13 |
167 |
| Change |
+ 20 |
- 13 |
|
| After |
1 u |
1 u |
174 |
Total number of stamps in the end
= 167 + 20 - 13
= 174
2 u = 174
1 u = 174 ÷ 2 = 87
Number of stamps that Ryan had in the end
= 1 u
= 87
Number of stamps that Ryan had at first
= 87 - 20
= 67
Answer(s): 67
