Question

A masonry contractor is preparing an estimate for building a stone wall and gate. He estimates that the job will take a​ 40-hour work week. He plans to have two laborers at ​$10 per hour and six masons at ​$21 per hour.​ He'll need ​$3337 worth of materials and wishes to make a profit of ​$400. Write a mathematical statement that will give the estimated cost of the job. Then calculate this total.

Answer 1

$9,577

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
