to build a 2.5 m by 3 m deck, a local building supply store chargers $1000 for materials, plus the 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? provide a full solution'

Answer 1

(1480 - 1000)/30 = h

Answer 2

A formula has to be written that takes all the money into account and the time that the carpenter's will spend on the deck.

We know that the store charges $1000 for materials and $30/hr on labor. So with that information we can say this:

$1000 + ($30 * t) = total

Where t is the time in hours, and because we know the total, $1480, we can say:

$1000 + ($30 * t) = $1480

Now all that is left is to solve for t:

$30 * t = $1480 - $1000

t = ($1480-$1000)/$30

t = $480/$30

t = 16h

Therefore, it will take the carpenters 16 hours to build the deck.
