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.
