Asked by Annie
Last year you mowed grass and shoveled snow for 10 households. You earned $200 per household mowing for the entire season & $180 per household for shoveling the entire season. If you earned a total of $1880 last year, how many households did you mow and shovel for?!
How would you set this up!! I know you have to do a system of equations! Thx in advance <3

M = 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.
