At the tourist attraction, there were
18 as many boys as girls. After 79 boys came and 26 girls left the tourist attraction, there was an equal number of boys and girls who remained at the tourist attraction. How many children were at the tourist attraction in the end?

Boys |
Girls |
| Before |
1 u |
8 u |
| Change |
+ 79 |
- 26 |
| After |
1 u + 79 |
8 u - 26 |
Number of children in the end is the same.
8 u - 26 = 1 u + 79
8 u - 1 u = 79 + 26
7 u = 105
1 u = 105 ÷ 7 = 15
Number of children in the end
= 2 x (1 u + 79)
= 2 u + 158
= 2 x 15 + 158
= 30 + 158
= 188
Answer(s): 188
