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 month month month = 52 200 pesos/ month
