At the office building, Level K and Level L had an equal number of tables at first. If 6 tables were removed from Level L and 5 times as many tables were removed from Level K as Level L, the number of tables in Level L would be 5 times as many as in Level K. Find the number of tables on each level.
| |
Level K |
Level L |
| Before |
1 u + 30 |
5 u + 6 |
| Change |
- 30 |
- 6 |
| After |
1 u |
5 u |
Number of tables removed from Level K
= 5 x 6
= 30
Number of tables on Level K and Level L at first is the same.
5 u + 6 = 1 u + 30
5 u - 1 u = 30 - 6
4 u = 24
1 u = 24 ÷ 4 = 6
Number of tables on each level
= 1 u + 30
= 6 + 30
= 36
Answer(s): 36
