Ali want to do wedding ceremony for 3 days which total cost is $12256. From the total cost, the hall  rental is $2000 per day. Therefore, please find the cost for per day for rental on car and lcd screen. However, the rental of car for 3 days is between $1500 until $2700. The answer for rent of car and rent of lcd screen cannot be decimal places.

Let's break down the given problem step-by-step to find the cost per day for renting the car and LCD screen.

### Given Information:
1. **Total cost for 3 days**: \$12,256
2. **Hall rental per day**: \$2,000
3. **Car rental for 3 days**: Between \$1,500 and \$2,700 (inclusive)
4. **Cost per day for car and LCD screen rental must be whole numbers.**

### Steps to Find the Cost per Day:

1. **Calculate the Total Hall Rental Cost for 3 Days:**
   \[
   \text{Total hall rental cost} = 3 \times 2000 = 6000 \, \text{USD}
   \]

2. **Subtract the Hall Rental Cost from the Total Cost:**
   \[
   \text{Remaining cost} = 12256 - 6000 = 6256 \, \text{USD}
   \]
   This remaining amount is the combined total cost for renting the car and the LCD screen for 3 days.

3. **Determine the Possible Cost Range for Car Rental:**
   The car rental for 3 days is between \$1,500 and \$2,700. We can denote the car rental cost for 3 days as $ C $, where:
   \[
   1500 \leq C \leq 2700
   \]

4. **Calculate the Cost for LCD Screen Rental:**
   Let the total cost for the LCD screen rental for 3 days be $ L $. Then:
   \[
   C + L = 6256
   \]
   Rearranging, we find:
   \[
   L = 6256 - C
   \]

   The daily costs for car rental and LCD screen rental, $ \frac{C}{3} $ and $ \frac{L}{3} $, must also be whole numbers. Thus, $ C $ must be divisible by 3.

### Find the Correct Cost for Car Rental (C):
We will check values for $ C $ within the range [1500, 2700] that are divisible by 3:

\[
\begin{align*}
C = 1500, & \quad \text{since } 1500 \div 3 = 500 \\
C = 1503, & \quad \text{since } 1503 \div 3 = 501 \\
C = 1506, & \quad \text{since } 1506 \div 3 = 502 \\
& \vdots \\
C = 2700, & \quad \text{since } 2700 \div 3 = 900 \\
\end{align*}
\]

### Determine the Corresponding LCD Screen Rental Costs:

We find a value for $ C $ such that $ L = 6256 - C $ is also divisible by 3. Let's check:

- If $ C = 2400 $:
  \[
  L = 6256 - 2400 = 3856, \quad \text{and} \quad 3856 \div 3 = 1285.33 \, (\text{not a whole number})
  \]
  
- If $ C = 1800 $:
  \[
  L = 6256 - 1800 = 4456, \quad \text{and} \quad 4456 \div 3 = 1485.33 \, (\text{not a whole number})
  \]

- If $ C = 1500 $:
  \[
  L = 6256 - 1500 = 4756, \quad \text{and} \quad 4756 \div 3 = 1585.33 \, (\text{not a whole number})
  \]

- If $ C = 2100 $:
  \[
  L = 6256 - 2100 = 4156, \quad \text{and} \quad 4156 \div 3 = 1385.33 \, (\text{not a whole number})
  \]

Continue until the cost combination is found which satisfies the integer requirements.
