Step-by-step explanation:
Given:
Estimated time for the job = 40 hours
Number of laborers = 2
Per hour laborers cost = $10
Number of masons = 6
Per hour mason cost = $21
Worth of material = $3337
Estimated Profit = $400
Now,
The total amount spent on laborers
= Number of laborers × total working hours × Cost per hour
= 2 × 40 × $10
= $800
The total amount spent on masons
= Number of masons × total working hours × Cost per hour
= 6 × 40 × $21
= $5040
Hence,
the total estimated cost for the job
The total amount spent on laborers $800
The total amount spent on masons $5,040
Worth of material $3,337
Estimated Profit $400
Total estimated cost $9,577
