An 8ft length of 4 inch wide crown molding costs $12. How much will it cost to buy 96 ft of crown molding?


To solve this problem, we first need to find the cost per foot of the crown molding and then multiply it by the total length required.

### Step-by-step solution:

1. **Determine the cost per foot:**

   The cost of 8 feet of crown molding is $12. Therefore, the cost per foot is:
   
   \[
   \text{Cost per foot} = \frac{\text{Total cost}}{\text{Length in feet}} = \frac{12}{8} = 1.5 \text{ dollars per foot}
   \]

2. **Calculate the cost for 96 feet:**

   Now, multiply the cost per foot by the total length required:

   \[
   \text{Total cost for 96 feet} = 1.5 \times 96 = 144 \text{ dollars}
   \]

### Conclusion:

The cost to buy 96 feet of crown molding will be **$144**.
