To build a 2.5m by 3m deck, a local building supply store chargess 1000 dolars for materials, plus carpenter's wage of $30/h. The store gives you an estimate of $1480 for the total cost. How much time is estimated for the carpenter to build the deck
Assuming no taxes, then the man-power charge is what is in excess of $1000, or $480. At $30 an hour, $480 will be equal to 480/30=16 hours.
To determine the estimated time for the carpenter to build the deck, we need to subtract the cost of materials from the total cost provided and divide the remaining amount by the carpenter's wage.
Total cost - Materials cost = Carpenter's wage * Time
Let's calculate it step-by-step:
1. Calculate the materials cost:
Materials cost = $1000
2. Calculate the remaining cost for the carpenter's wage:
Remaining cost = Total cost - Materials cost = $1480 - $1000 = $480
3. Calculate the estimated time:
Carpenter's wage * Time = Remaining cost
$30/h * Time = $480
4. Divide both sides of the equation by $30 to solve for Time:
Time = $480 / $30
5. Calculate the estimated time for the carpenter to build the deck:
Time = 16 hours
Therefore, the estimated time for the carpenter to build the deck is 16 hours.
To calculate the estimated time for the carpenter to build the deck, we first need to determine the cost of the carpenter's wage.
The total cost of $1480 includes the cost of materials ($1000) and the carpenter's wage. Therefore, we can find the cost of the carpenter's wage by subtracting the cost of materials from the total cost:
Carpenter's wage = Total cost - Cost of materials
Carpenter's wage = $1480 - $1000
Carpenter's wage = $480
Now that we have the carpenter's wage, we can calculate the estimated time. Given that the carpenter charges $30 per hour, we can divide the carpenter's wage by the hourly rate to find the estimated time:
Estimated time = Carpenter's wage / Hourly rate
Estimated time = $480 / $30
Estimated time = 16 hours
Therefore, the estimated time for the carpenter to build the deck is 16 hours.
