There are actually 2 solutions to this problem. Since you have 1 equation with 2 unknowns that will be the case.
The two answers are:
10 Mow
3 The Works
and
2 Mow
8 The works
Given the wording, if you know there should only be one solution, I would state that 2 Mow/8 The works would be the desired answer. The "Some of the neighbors" statement implies, fewer customers take the Mow only option than that of "the works".

Let x be the number for mowing and y for the "works"
25x + 40y = 370
