Final answer:
The total cost for remodeling the deck with 8 hours of labor is $250, based on the given cost function C(x) = 25x + 50.
Step-by-step explanation:
The function C(x) = 25x + 50 represents the cost of remodeling a deck, where x is the number of hours of labor. To calculate the total cost for remodeling the deck estimated to take 8 hours of labor, we substitute x with 8 in the function.
So, C(8) = 25(8) + 50.
Now, we do the math: C(8) = (25 × 8) + 50 = 200 + 50 = $250.
Therefore, the total cost to remodel the deck for 8 hours of labor is $250.
