Cost of siding = _____3. How much would the windows cost? _____4. What would be the total cost of the remodeling job materials? _____

Respuesta :

Since the area of siding is 1800 square feet

Since each box of siding cover 100 square feet

Then divide them to find the number of siding boxes is needed

[tex]\begin{gathered} N=\frac{1800}{100} \\ \\ N=18 \end{gathered}[/tex]

1. 18 siding boxes are needed

Since the cost of each siding box is $220.41, then

Multiply 18 by 220.41 to find the cost of siding

[tex]\begin{gathered} C=18\times220.41 \\ \\ C=\text{ \$}3967.38 \end{gathered}[/tex]

2. Cost of siding = $3967.38

Since there are 15 windows

Since the cost of each window is $275.00, then

Multiply 15 by 275.00 to find the cost of all windows

[tex]\begin{gathered} W=15\times275.00 \\ \\ W=\text{ \$}4125.00 \end{gathered}[/tex]

3. The windows cost $4125.00

To find the total cost of the remodeling job materials add the 2 costs above

[tex]\begin{gathered} T.C=3967.38+4125.00 \\ \\ T.C=\text{ \$}8092.38 \end{gathered}[/tex]

4. The total cost of the remodeling job material is $8092.38
