Answer:
- 4350 +35m ≥ 5000
- m ≥ 18.57
Explanation:
The number on hand (4350) plus the number that can be filled in m minutes (35m) must be at least 5000:
4350 + 35m ≥ 5000 . . . . the inequality you can solve
__
35m ≥ 650 . . . . . . subtract 4350
m ≥ 650/35 . . . . . divide by 35
m ≥ 18.57 . . . . . . . rounded to hundredths
It would take at least 18 4/7 minutes to fill enough bottles.
