Answer:
The total cost of the crown molding is $23.43.
Step-by-step explanation:
Given:
Tom's dad is putting crown molding around the top of all of the walls in Tom's bedroom.
The dimensions of his bedroom are 1 3/4 and 15 3/4.
Each foot of crown molding costs $.85.
Now, to find the total cost of the crown molding.
The dimensions are:
[tex]1\frac{3}{4}\ feet \ and\ 15\frac{3}{4} \ feet.[/tex]
[tex]\frac{7}{4}\ feet\ and\ \frac{63}{4} \ feet.[/tex]
So, to get the area of bedroom:
[tex]\frac{7}{4} \times \frac{63}{4}[/tex]
= [tex]\frac{441}{16} \ feet.[/tex]
As given, each foot of crown molding costs $.85.
Now, to get the total cost of crown molding:
[tex]0.85\times \frac{441}{16}[/tex]
[tex]=\frac{374.85}{16}[/tex]
[tex]=\$23.43.[/tex]
Therefore, the total cost of the crown molding is $23.43.
