Answer 1

The cost to buy 32 ft of crown molding is $48.00. This is found by calculating the cost per foot of the molding and then multiplying by the total length needed.

Step-by-step explanation:

The correct option : a

To calculate the cost of 32 ft of crown molding, we can set up a proportion based on the given information that 8 ft of the molding costs $12. We start by determining the cost per foot of the molding:

Now, we calculate the cost for 32 ft:

• Total cost = Cost per foot × Length in feet
• Total cost = $1.50 per foot × 32 ft
• Total cost = $48.00

Therefore, the cost to buy 32 ft of crown molding is $48.00,
