If x is the number of small lawns and y is the number of large lawns, which ordered pair is a solution to the system of inequalities which describes Jeff's situation?

**Steve**, Wednesday, May 9, 2012 at 1:10pmDon't see any choices, but we do know

2x + 3y <= 20

25x + 35y >= 250

If he does 10 small lawns, that's 20 hrs and $250

He can't do any large lawns, since he can do at most 8 small lawns for $200, and can't make up the difference and stay under 20 hours:

S L Hrs $$$

10 0 20 250

9 0 18 225

8 1 19 235

7 2 20 245

6 2 18 220
