1.four men can paint a house in 24 days.the owner wants the painting job to be finished in 12 days. how many should he hire?
----
# of men is inversely related to # of days
m = k/d
Solve for "k"::
4 = k/24
k = 96
----
Equation::
m = 96/12 = 8 men
----------
2.if 12 men can do the job in eight days. how long it take 16 men to do the same job?
-----
12 = k/8
k = 96
Equation:
m = 96/d
16 = 96/d
d = 96/16
d = 6 days
----------
