How would you set this up!! I know you have to do a system of equations! Thx in advance <3

**drwls**, Tuesday, February 9, 2010 at 8:49pmM = number of mowing jobs

S = number of snow shoveling jobs

M + S = 10

200M + 180 S = 1880

======================

Multiply the first equation by 200

200M + 200 S = 2000

Subtract the last two.

20 S = 120

S = 6

etc.
