A masonry contractor is preparing an estimate for building a stone wall and gate. He estimates that the job will take a​ 40-hour
kodGreya [7K]

Solution: Estimated time for the work is 40 hour work week.

Estimated payment to 3 laborers working 40 hours at cost $14 per hour is:

3\times 40\times 14= $1680

Estimated payment to 6 masons working 40 hours at cost $24 per hour is:

6\times 40\times 24= $5760

Estimated cost of material = $3143

Contractor wishes to make a profit of $500

Therefore, the mathematical expression that will give the estimated cost of the job is:

Cost = 1680+5760+3143+500

The estimated total cost is:

Cost =$11083
