Reggie and Ethan had a total of 233 buttons at first. After Reggie bought 22 more buttons and Ethan gave away 15 buttons, Reggie now has the same number of buttons as Ethan. How many buttons did Reggie have at first?
| |
Reggie |
Ethan |
Total |
| Before |
1 u - 22 |
1 u + 15 |
233 |
| Change |
+ 22 |
- 15 |
|
| After |
1 u |
1 u |
240 |
Total number of buttons in the end
= 233 + 22 - 15
= 240
2 u = 240
1 u = 240 ÷ 2 = 120
Number of buttons that Reggie had in the end
= 1 u
= 120
Number of buttons that Reggie had at first
= 120 - 22
= 98
Answer(s): 98
