Gabriel and Harry had a total of 186 marbles at first. After Gabriel bought 22 more marbles and Harry gave away 18 marbles, Gabriel now has the same number of marbles as Harry. How many marbles did Gabriel have at first?
|
Gabriel |
Harry |
Total |
Before |
1 u - 22 |
1 u + 18 |
186 |
Change |
+ 22 |
- 18 |
|
After |
1 u |
1 u |
190 |
Total number of marbles in the end
= 186 + 22 - 18
= 190
2 u = 190
1 u = 190 ÷ 2 = 95
Number of marbles that Gabriel had in the end
= 1 u
= 95
Number of marbles that Gabriel had at first
= 95 - 22
= 73
Answer(s): 73
