Last year you mowed grass and shoveled snow for 10 households. You earned $200 per household mowing for the entire season and $180 per household shoveling for the entire season. You earn a total of $1880 last year. Write and solve an algebraic model to determine the number of households you mow and shovel for.
---------------
Quantity Eq:: m + s = 10 households
Value Eq::: 200m+180s = 1880 dollars
--------------------
Modify for elimination::
10m + 9s = 94
10m + 10s = 100
----
Subtract and solve for "s", then solve for "m":::
s = 6 (# shoveled)
m = 4 (# mowed)
