CSLB C-27 Landscaping ContractorPlanning and EstimatingEasy
A C-27 contractor is estimating the cost for a new residential landscape project that includes a 300 square foot paver patio. The estimated material cost for pavers is $4.50 per square foot, and the labor cost for installation is $7.00 per square foot. What is the total estimated material and labor cost for the paver patio?
- A$3,450
- B$1,350
- C$4,050
- D$2,100
Show answer & explanationAnswer & explanation
Correct answer: A. $3,450
To find the total cost, first calculate the material cost (300 sq ft * $4.50/sq ft = $1,350) and the labor cost (300 sq ft * $7.00/sq ft = $2,100). Then, add these two amounts together ($1,350 + $2,100 = $3,450).
Why the other options are wrong
- B. This only accounts for the material cost ($4.50 * 300 sq ft = $1,350).
- C. This is an incorrect calculation; possibly adding material and labor rates and then multiplying by area, but with an error.
- D. This only accounts for the labor cost ($7.00 * 300 sq ft = $2,100).
Combined Cost Calculation
The process of summing different cost components (e.g., material, labor) for a specific project item to determine its total cost.
- Essential for accurate bidding.
- Involves identifying all relevant cost factors.
- Often calculated per unit or area.
Memory trick: Material plus labor, then multiply by the area for the total.
