Question

Last year you mowed grass or shoveled snow
for 12 households. You charged $200 a season
to mow a yard and $180 a season to shovel
snow. You earned $2280 last year.
How many households did you mow

Answer 1

x=number of households mowed
y=number of households shoveled snow for
x+y=12
200x+180y=2280

from the first equation we get y=12-x replace it in the second

200x + 2160 - 180x = 2280
20x = 120
x=6

Answer 2

Answer 3

y=12-x = 6 also
it is the number of households shoveled snow for
