Answer:
At least 45 sets of forks to be bought
-----------------------------
Given
- Forks available = 287,
- Forks needed - at least 732,
- Number of sets required = x,
- Size of each set = 10.
Required inequality is
- x sets of 10 and 287 in total is at least 732
- 10x + 287 ≥ 732
- 10x ≥ 732 - 287
- 10x ≥ 445
- x ≥ 445/10
- x ≥ 44.5 = 45 (rounded to the whole number)
