Answer:
Hand saw is cheaper.
Explanation:
Given:
Material cost = $500
Electric saw cost rent per hour = $20
Building hour from electric saw = 6 hour
Building hour from hand saw = 15 hour
Time off pay from job = $8/hour
Computation of total cost from Electric saw :
Total cost from Electric saw = Material cost + Renting cost of electric saw + Time of from job
Total cost from Electric saw = $500 + (6 × $20) + (6 × $8)
Total cost from Electric saw = $500 + $120 + $48
Total cost from Electric saw = $668
Computation of total cost from hand saw :
Total cost from hand saw = Material cost + Time of from job
Total cost from hand saw = $500 + (15 × $8)
Total cost from hand saw = $500 + $120
Total cost from hand saw = $620
Hand saw is cheaper.
