A company has a contract to build a sewer in a nearby province, It must dig a

ditch 2m wide, 1m deep, and 2000m long. Laborers are available at P 120/day

for an 8-hr day work and can dig at an average of 0.5 cu-m per hr. A ditch-

digging machine maybe rented at a cost of P 1,500 a day for all the time it is

in use or in transit. One day would be required for transporting the machine

one way. Freight cost would total P 4,000. The machine operator would be

paid P350/day including travel time for two days. If the machine is used, three

laborers are needed. The ditch digging machine can excavate 1 cu-m in 6 min. All workers and machine rentals must be paid on full 8-hr a day basis. What

would you recommend and by how much it must cost?
