At the factory, Level E and Level F had an equal number of machines at first. If 8 machines were removed from Level F and 4 times as many machines were removed from Level E as Level F, the number of machines in Level F would be 4 times as many as in Level E. Find the number of machines on each level.
| |
Level E |
Level F |
| Before |
1 u + 32 |
4 u + 8 |
| Change |
- 32 |
- 8 |
| After |
1 u |
4 u |
Number of machines removed from Level E
= 4 x 8
= 32
Number of machines on Level E and Level F at first is the same.
4 u + 8 = 1 u + 32
4 u - 1 u = 32 - 8
3 u = 24
1 u = 24 ÷ 3 = 8
Number of machines on each level
= 1 u + 32
= 8 + 32
= 40
Answer(s): 40
