Computation
Let x be the total wage of the foreman in a
month
x = daily wage X entire days
= 400 pesos X 30 days
1day
= 400 pesos X 30 days
1day
1 month
= 12000 pesos/ month
Computation
Let y be the total wage of the skilled worker in a
month
y = daily wage X entire work days
= 350 pesos X 30 days
1day
= 350 pesos X 30 days
1day
1 month
= 10500 pesos/ month
2y = 2 ( 10500 pesos/ month) = 21000 pesos/ month
Computation
Let z be the total wage of the unskilled worker in a
month
z = daily wage X entire work days
= 250 pesos X 30 days
1day
= 250 pesos X 30 days
1day
1 month
= 7500 pesos/ month
4z = 4 ( 7500 pesos/ month) = 30000 pesos/ month
Computation of the cost of
the entire job
Let n be the total cost of the entire job
n = x + 2y + 4z
= 1200 pesos + 21 000 pesos + 30 000 pesos

= 52 200 pesos/ month
