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.
