ELEN [110]

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:

$1\frac{3}{4}\ feet \ and\ 15\frac{3}{4} \ feet.$

$\frac{7}{4}\ feet\ and\ \frac{63}{4} \ feet.$

So, to get the area of bedroom:

$\frac{7}{4} \times \frac{63}{4}$

= $\frac{441}{16} \ feet.$

As given, each foot of crown molding costs $.85.

Now, to get the total cost of crown molding:

$0.85\times \frac{441}{16}$

$=\frac{374.85}{16}$

$=\$23.43.$

Therefore, the total cost of the crown molding is $23.43.
