3. A contractor won a bid to repave so many kilometers of a badly damaged concrete road in the south. He
is offered a crane-mounted pneumatic breaker which will cost P 1,200,000 with a salvage value of P
150,000 at the end of its estimated life of 15 years. The annual cost of maintenance, taxes, licenses and
insurance is 12% of the first cost, regardless of how the equipment is used. The variable cost is P 550 per
day. The equipment is capable of breaking 30 sq.m. of 20-centimeter-thick of concrete road per day.
Without equipment, two laborers receiving P 50 each per day could break an average of one sq.m. of the
same road per day. How many sq.m. of the road per year must the equipment break to make the machine
an economical investment? Assume interest on investment to be 12% of the first cost.
