Answer:

The total cost to build the deck equals the cost of the materials and the cost of the carpenters wage.

Let "y" equal the total cost and let x equal the hours.

Algebraically: y= 30x+1000

substitute 1480 for the total cost "y"

1480=30x+1000

1480-1000=30x

480=30x

480/30= 30/30x

x=6

or it will take six hours to build the deck.
