Answer 1

The material cost is: $875

The cost of building a wooden deck, including the material and labor, is 30% of the material cost.

The expression to calculate the total cost is,

$\begin{gathered} \text{Total Cost=875(1+}\frac{30}{100}\text{)} \\ =875\times(\frac{13}{10}) \\ =\frac{2275}{2} \\ =1137.5 \end{gathered}$

Thus, the total cost is $ 1137.5.
