At the office building, Level F and Level G had an equal number of chairs at first. If 8 chairs were removed from Level G and 3 times as many chairs were removed from Level F as Level G, the number of chairs in Level G would be 5 times as many as in Level F. Find the number of chairs on each level.
| |
Level F |
Level G |
| Before |
1 u + 24 |
5 u + 8 |
| Change |
- 24 |
- 8 |
| After |
1 u |
5 u |
Number of chairs removed from Level F
= 3 x 8
= 24
Number of chairs on Level F and Level G at first is the same.
5 u + 8 = 1 u + 24
5 u - 1 u = 24 - 8
4 u = 16
1 u = 16 ÷ 4 = 4
Number of chairs on each level
= 1 u + 24
= 4 + 24
= 28
Answer(s): 28
